Which of the following correctly states the quantisation of charge?
ACharge on any body is always an integral multiple of the elementary charge e
BCharge on any body is always positive
CCharge on any body must be a multiple of one coulomb
DCharge on any body can take any continuous real value
Answer & Solution
Correct answer: A. Charge on any body is always an integral multiple of the elementary charge e
Quantisation of charge means q = n·e where n is an integer and e ≈ 1.6×10⁻¹⁹ C. Charges therefore come in discrete steps, not continuous values.
