Answer:
[tex]3.75*10^{-13}[/tex] electrons
Explanation:
The total charge Q is the sum of the charge of the N electrons contained in the sphere:
[tex]Q=N*q_{e}[/tex]
[tex]q_{e}=-1.6*10^{-19}C[/tex] charge of a electron
We solve to find N:
[tex]N=\frac{Q}{q_{e}}=\frac{-6 x 10^{-6}}{-1.6 x 10^{-19}}=3.75*10^{-13}[/tex]
