A conducting sphere has a net charge of -4.8x10-17 C. What is the approximate number of excess electrons on the sphere?

Aloiza [94]

Answer:

The number is $N = 300$

Explanation:

From the question we are told that

The net charge is $Q = -4.8 *10^{-17 } \ C$

Generally the charge on a electron is $e = - 1.60 *10^{-19 } \ C$

Generally the number of excess electrons is mathematically represented as

$N = \frac{Q}{e}$

=> $N = \frac{-4.8 *10^{-17}}{-1.60 *10^{-19}}$

=> $N = 300$
