1Two point charges separated by a distance r in air exert a force F on each other. If the distance between them is doubled (2r), what is the new electrostatic force?

A.2F

B.F/2

C.F/4

D.4F

Explanation: According to Coulomb's Law, electrostatic force is inversely proportional to the square of the distance between charges (F ∝ 1/r²). Doubling the distance (2r) reduces the force to F/4.

2Which of the following represents the correct SI unit of electric flux?

A.Volt per meter (V/m)

B.Volt-meter (V·m)

C.Newton per Coulomb (N/C)

D.Coulomb per square meter (C/m²)

Explanation: Electric flux is defined as Φ = E · A. Since electric field E is in V/m and area A is in m², the SI unit is (V/m) × m² = V·m (Volt-meter) or N·m²/C.

3A point charge +q is placed at the center of a cube of side a. What is the electric flux passing through one face of the cube?

A.q / ε₀

B.q / (6 ε₀)

C.q / (4 ε₀)

D.6 q / ε₀

Explanation: By Gauss's Law, total electric flux through the entire enclosed cube is Φ_total = q / ε₀. Since a cube has 6 symmetric faces, the flux through any single face is (1/6) × (q / ε₀) = q / (6 ε₀).

4An electric dipole of dipole moment p is placed in a uniform electric field E. At what angle θ between p and E does the dipole experience maximum torque?

A.0°

B.45°

C.90°

D.180°

Explanation: The torque acting on an electric dipole in a uniform electric field is given by τ = p × E = p E sin θ. The torque reaches its maximum magnitude (τ_max = p E) when sin θ = 1, corresponding to θ = 90°.

5How does the electrostatic potential V due to a single point charge depend on distance r from the charge?

A.V ∝ 1/r

B.V ∝ 1/r²

C.V ∝ r

D.V ∝ 1/r³

Explanation: The electric potential V due to a point charge q at distance r is given by V = (1 / 4πε₀) · (q / r). Thus, electric potential is inversely proportional to distance r (V ∝ 1/r).

6A parallel plate capacitor with plate area A and separation d is filled with a dielectric slab of dielectric constant K and thickness t (t < d). What is its capacitance C?

A.C = ε₀ A / [d - t (1 - 1/K)]

B.C = K ε₀ A / d

C.C = ε₀ A / (d - t)

D.C = K ε₀ A / (d + t)

Explanation: When a dielectric slab of thickness t is inserted, the effective air separation becomes (d - t) and dielectric thickness is t. The combined potential difference yields C = ε₀ A / [d - t(1 - 1/K)].

7Two capacitors of capacitances 3 μF and 6 μF are connected in series across a voltage source. What is their equivalent capacitance?

A.9 μF

B.2 μF

C.4.5 μF

D.18 μF

Explanation: For two capacitors connected in series, equivalent capacitance C_eq is calculated as 1/C_eq = 1/C₁ + 1/C₂, or C_eq = (C₁ × C₂) / (C₁ + C₂). Here, C_eq = (3 × 6) / (3 + 6) = 18 / 9 = 2 μF.

8What is the work done in rotating an electric dipole of dipole moment p through 180° starting from stable equilibrium (θ = 0°) in a uniform electric field E?

A.p E

B.2 p E

C.zero

D.-2 p E

Explanation: Work done in rotating a dipole from angle θ₁ to θ₂ in a uniform electric field is W = p E (cos θ₁ - cos θ₂). For θ₁ = 0° and θ₂ = 180°, W = p E (cos 0° - cos 180°) = p E (1 - (-1)) = 2 p E.

9What is the electric field intensity inside a uniformly charged thin spherical conducting shell of radius R?

A.Zero

B.q / (4πε₀ R²)

C.σ / ε₀, where σ is the surface charge density of the shell

D.Infinite

Explanation: Inside a charged thin spherical conducting shell, all charges reside on the outer surface. A Gaussian surface drawn inside encloses zero net charge, so by Gauss's Law, E = 0 everywhere inside.

10A 10 μF capacitor is charged to a potential difference of 100 V. What is the electrostatic energy stored in the capacitor?

A.0.05 J

B.0.5 J

C.0.1 J

D.1.0 J

Explanation: Energy stored in a capacitor is U = (1/2) C V². Converting C = 10 μF = 10 × 10⁻⁶ F: U = 0.5 × (10 × 10⁻⁶ F) × (100 V)² = 0.5 × 10⁻⁵ × 10⁴ = 0.05 Joules.
