Part B contains eight questions, numbered 21 to 28. Students must answer any five questions for ten marks.
| Question | Topic |
|---|---|
| 21 | Write two properties of electric field lines. |

The Scheme of Evaluation gives the final magnetic field as 4 × 10-6 T.
The calculation carries two marks, with marks allocated to the formula and correct substitution or result.
Question 25 – Motional EMF
Students must write the expression for the emf induced in a straight conductor moving perpendicular to a uniform magnetic field.
Formula: ε = Blv
Here B is magnetic field strength, l is the length of the conductor and v is its velocity.
Other Important Two-Mark Concepts
The Scheme of Evaluation identifies microwaves for aircraft radar and ultraviolet radiation for the LASIK question. It also states that the alpha-particle scattering angle is 180 degrees for zero impact parameter.
For semiconductor resistivity, students should explain that resistivity generally decreases as temperature increases and draw the requested variation graph.
Part C – Three-Mark Physics Questions
Part C contains Questions 29 to 36. Students must answer any five questions for 15 marks.

A refracting telescope has an objective focal length of 144 cm and a tube length of 150 cm.
The solution uses:
- Focal length of eyepiece = 150 − 144 = 6 cm.
- Magnification = 144 / 6 = 24.
The Scheme of Evaluation allocates marks to the focal-length relationship, magnification formula and final calculation.
Question 35 – Photoelectric Effect
Students should revise experimental observations such as instantaneous photoelectric emission, threshold frequency, dependence of photocurrent on light intensity and the dependence of maximum kinetic energy on incident frequency.
Any three relevant observations are required according to the evaluation scheme.

Question 37 – Gauss's Law
Question 37 requires students to derive the electric field due to an infinitely long uniformly charged straight wire.
The derivation uses a cylindrical Gaussian surface and the electric flux relation.
Final Expression: E = λ / (2πε₀r)
The five marks are distributed across the appropriate Gaussian surface, flux expression, enclosed charge and derivation of the electric field.
Question 38 – Cells Connected in Series
Students must derive the equivalent emf and equivalent internal resistance of two cells connected in series.
For the series-aiding arrangement shown in the evaluation scheme, the results are:
- Equivalent emf: εeq = ε₁ + ε₂.
- Equivalent internal resistance: req = r₁ + r₂.
The scheme awards marks for the circuit arrangement, terminal potential expressions, combination of the equations and the final results.
Question 39 – Magnetic Field on the Axis of a Circular Loop
Question 39 requires the derivation of magnetic field strength at a point on the axis of a circular current-carrying loop.
Final Expression: B = μ₀IR2 / [2(R2 + x2)3/2]
Students should show the circular-loop diagram, the relevant Biot-Savart law expression, symmetry considerations and integration around the loop.
Question 40 – Concave Mirror Formula

Part D, Section VI, contains four numerical questions numbered 42 to 45. Students must answer any two questions for ten marks.
| Question | Numerical Topic |
|---|---|
| 42 | Positions of zero electric potential due to two point charges. |
| 43 | Resistance, electric current and current density of a wire. |
| 44 | Inductance of a series RL alternating-current circuit. |
| 45 | Young's double-slit interference using two wavelengths. |
Question 42 – Zero Electric Potential
Two electric charges of +5 × 10-8 C and −3 × 10-8 C are separated by 16 cm in vacuum.
Students must find the two positions along the line joining the charges at which the electric potential is zero.
The Scheme of Evaluation gives two positions:
- 10 cm from the positive charge, between the charges.
- 40 cm from the positive charge, beyond the negative charge.
Students should apply the algebraic sum of the two electric potentials and show the complete calculation.
Question 43 – Resistance, Current and Current Density
Question 43 provides the length, cross-sectional area, resistivity and power dissipation of a conducting wire.
Students must calculate resistance, current and current density.

| Resistance | R = ρl/A | 2.5 Ω |
| Electric Current | I = √(P/R) | 2 A |
| Current Density | J = I/A | 1 × 107 A/m² |
Students should practise unit conversion carefully when the cross-sectional area is given in scientific notation.
Question 44 – Inductance in an RL Circuit
An inductor and a resistor are connected in series with a 200 V, 50 Hz AC supply. The current is 2 A and the voltage leads the current by an angle of π/3.
Students must calculate the inductance using the circuit impedance and inductive reactance.
The Scheme of Evaluation gives:
- Impedance Z = 100 Ω.
- Inductive reactance = 86.6 Ω.
- Inductance L = 0.276 H, approximately 0.28 H.
Question 45 – Young's Double-Slit Experiment
The examination question uses two wavelengths, 500 nm and 600 nm, in Young's double-slit experiment.
The distance between the slits is 1 mm and the screen is placed 1.2 m away.
Students must calculate:
- The least distance from the central maximum where the bright fringes of both wavelengths coincide.
- The distance of the third dark fringe for the 500 nm wavelength from the central bright fringe.
The Scheme of Evaluation gives the following answers:
| Calculation | Result |
|---|---|
| First common bright fringe position | 3.6 mm |
| Third dark fringe position for 500 nm | 1.5 mm |
Students should use the interference-fringe formulas and show the conversion of wavelength, slit separation and screen distance into compatible units.
