Apiece of amber is charged by rubbing with a piece of fur. if the net excess charge on the fur is 8.9 nc ( 8.9 10-9 c), how many electrons were added to the amber

Number of electrons,

Explanation:

Given that,

Charge on the fur,

A piece of amber is charged by rubbing with a piece of fur. We need to find the electrons were added to the amber. It can be calculated using the quantization of charge as

q = n × e

Where

n is the number of electrons

e is the charge on electron

So, number of electrons are added to the amber. Therefore, this is the required solution.

i think the answer is a, hope this : )
