Q. In nature, the electric charge of any system is always equal to
A) Half integral multiple of the least amount of charge
B) Zero
C) Square of the least amount of charge
D) Integral multiple of the least amount charge
Explanation
(d) If the charge of an electron is taken as elementary unit $ie,$ quanta of charge, the charge on anybody will be some integral multiple of $e\ ie,\ q = n\ e\ with\ n = 1,2,3\ldots$
