Question

How many electrons should be removed from a conductor so that it acquires a positive charge of 3.5 nC ?
​

Answer 1

Answer:

n=10

Explanation:

Given

Charge q=3.5×10

−9

Let the nQ of electron to be removed be n

We know that

Q=ne

n=

e

Q

n=

1.6×10

−19

3.5×10

−9

n=2.1875×10

−9+19

n=2.1875×10

10
