Question

a conducting sphere has a net charge of -4.8x 10^-17.what is the approximate number of excess electrons on the sphere ​

Answer 1

Explanation:

Charge on one e = 1.6*10^-19

Net charge = 4.8 *10^ - 17

Excess electron = q/e = 300

Answer 2

There are 300 excess electrons on the sphere .

Explanation:

Given that,

A conducting sphere has a net charge of, $q=-4.8\times 10^{-17}\ C$

We need to find the number of excess electrons on the sphere. Using quantization of charge as follows :

$q=ne$

n is number of excess electrons on the sphere ​

$n=\dfrac{q}{e}\\\\n=\dfrac{4.8\times 10^{-17}}{1.6\times 10^{-19}}\\\\n=300$

So, there are 300 excess electrons on the sphere .
