Question

How many electrons must be removed from a piece of metal to give it a positive charge of 1.0*10^(-7)c

Answer 1

6.25 × 10^11 Charges must be removed from the plate of metal

Explanation:

We know that,

Q = ne             ………………. (i)

Where n is the number of charges removed.

As given in the question,

Q = 1.0 × 10^(-7) C

e = 1.6 × 10^(-19) C

By putting these values in equation (i) and solving for n we get,

n = 6.25 × 10^11  

Answer 2

Answer:

the answer is

6.25*10^11
