A conductor has a net charge of + 24 uC. How many electrons are needed to make this conductor neutral

The charge on the conductor is + 24 μC, since the charge is positive, same amount of charge but it will be negative.

That is - 24 μC.

To know the number of electrons, we know that the charge of an electron =

-1.6 * 10^-19 C.

= - 24 μC / (-1.6 * 10^-19 C)

= (-24 * 10^-6) / (-1.6 * 10^-19 C) Use your calculator

= 15 * 10^13

= 1.5 * 10 ^14 Electrons.
