Charging of solids by friction occurs due to the transfer of:
- Atoms
- Protons
- Neutrons
- Electrons
Show answer and explanation
Answer: D. Electrons
Only the loosely bound electrons move from one body to the other during rubbing.

SI unit of electric potential is:
- Ω C⁻¹
- V C⁻¹
- N C⁻¹
- J C⁻¹
Show answer and explanation
Answer: D. J C⁻¹
Potential = work/charge, so 1 volt = 1 joule per coulomb (J C⁻¹).
Capacitance C is:
- C = VQ
- C = V²Q
- C = Q/V
- C = V/Q
Show answer and explanation
Answer: C. C = Q/V
Capacitance = charge stored per unit potential difference, C = Q/V (farad).
What happens when like charges are brought near each other?
- They combine
- No force acts on these
- They attract
- They repel
Show answer and explanation
Answer: D. They repel
Like charges repel; unlike charges attract.
According to Coulomb's law: F =
- Kr/(q₁²q₂²)
- Kq₁²q₂²/r
- Kq₁q₂/r²
- Kq₁q₂r²
Show answer and explanation
Answer: C. Kq₁q₂/r²
F = k q₁q₂/r², k = 9 × 10⁹ N m² C⁻².
Potential difference between two points is 20 V. The work needed to shift 10 coulomb charge from one point to the other will be:
- 10 J
- 100 J
- 200 J
- 2 J
Show answer and explanation
Answer: C. 200 J
W = qV = 10 × 20 = 200 J.
What is meant by electric field? How does it affect a test charge placed in it? Explain briefly.
Show model answer
An electric field is the region around a charged body in which another charge experiences an electric force. Its strength at a point is E = F/q₀ (N C⁻¹).
A positive test charge placed in the field experiences a force F = q₀E in the direction of the field (away from a positive source charge, towards a negative one); a negative charge experiences a force opposite to the field. The charge is accelerated along the field lines; the closer the lines, the stronger the force.
Two capacitors of capacitance 3.0 F and 4.0 F are connected in series with the external source of voltage 150 V. Calculate the total capacitance.
Show model answer
Series: 1/Ce = 1/3 + 1/4 = 7/12 ⇒ Ce = 12/7 ≈ 1.71 F
(The charge on each capacitor would be Q = CeV = 1.71 × 150 ≈ 257 C.)
