Question

the quantisation of charge requires that a charge on a body always remain the integral multiple of charges in an electron.explain.

Answer 1

Quantization of charge states that the magnitude of charge on a body must be an integral multiple of the magnitude of charge of an electron.

The magnitude of the minimum charge a body can have is 1.6 × 10^-19 C. Charge of any other magnitude will always be an integral (1, 2, 3, 4, …..) multiple of the charge on the electron.
