How many electrons must be removed from an electrically neutral silver dollar to give it a charge of +3.5x10^-6C?

Explanation:

The electron is a fundamental particle, with a charge of

which is also known as fundamental charge.

For an object having N excess electrons, the total charge on the object is

(1)

where e is the charge of the electron.

For the object in this problem, its charge is

This can be obtained by removing a negative charge equal to

Substituting into (1) and solving for N, we can find the number of electrons:

answer would be d.) i hope this
