Question

How many electrons must be remowel from an electricaly Nurutral Silvor Coin to five it a charge of 3.2 NC ?

Answer 1

Answer:

 #_electrons = 2 10¹⁰ electrons

Explanation:

For this exercise we can use a direct rule of three proportions rule. If an electron has a charge of 1.6 10⁻¹⁹ C how many electrons have a charge of 3.2 10⁻⁹ C

          #_electrons = 3.2 10⁻⁹ ( $\frac{1}{1.6 \ 10^{-19}}$)

          #_electrons = 2 10¹⁰ electrons
