Question

The minimum charge on an object is __________.

Answer 1

Solution:

We know, charge is always an integral multiple of electronic charge, i.e.,

$Q=\pm ne$

where,

$Q\to$ is the charge on the object

$n\to$a integer

$e\to$electronic charge = $1.6\times {10}^{-19}coloumb$

$\because$ The minimum charge possible on an object is when $n=1$,i.e.,

$Q=e=1.6\times {10}^{-19}C$

The minimum charge on an object is $1.6\times {10}^{-19}coloumb$.
