alleryQuantisation of electric charge means:
ACharge can take any continuous value
BAll free charges are integral multiples of the elementary charge e (1.602 × 10⁻¹⁹ C)
COnly positive charges are quantised
DCharge is always zero
Answer & Solution
Correct answer: B. All free charges are integral multiples of the elementary charge e (1.602 × 10⁻¹⁹ C)
**Quantisation of charge**: q = ne, where n is an integer (positive or negative) and e = 1.602 × 10⁻¹⁹ C (charge on proton; electron has -e).
At macroscopic scales (1 μC ≈ 6 × 10¹² electrons) quantisation is unobservable
matters only at microscopic level.
