Question

A conducter has a total charge of 8.0 ×10^(-19) coulomb which is negative . Calculate the excess number of Election on it

Answer 1

Answer:

There are 5 excess electrons on the conductor.

Explanation:

The total charge on any material is given by  Q = ne. Where Q is the total charge , n is the number of particles , e is the charge of electron.In the question the number of electrons(Particles) is asked.So by the equation

Q = ne

Q = - 8.0 x 10^(-19)

e = -1.6 x 10^(-19)

=> Q/e = -8.0 x 10^(-19) /-1.6 x 10^(-19) = 5 = n
