the amount of charge present in a body,either positive or negative, is expressesd in term of an intergal multiple of the charge of an electron. can you explain its meaning?

Solution

The magnitude of charge on a body must be an integral multiple of the magnitude of charge of an electron.This is called quantization of charge.
The magnitude of the minimum charge a body can have is 1.6 × 10 ^-19C. Charge of any other magnitude will always be an integral (1, 2, 3, 4, …..) multiple of the charge on the electron.
Now, ‘e’ is the magnitude of the charge on an electron. So e = 1.6 × 10 ^-19 C.
Thus, the charge on a charged-body is always, q = ne, where n = 1, 2, 3, 4, .......
