Question

What is the charge on 4 electrons ? Explain the mathematical working​

Answer 1

Answer:

Electrons aren't made of quarks, but have a charge of -1. Knowing this, the total charge of protons is (4*1) = +4, the total charge of neutrons is (5 * 0) = 0, and the total charge of electrons is (3*-1) = -3. Add them up and you get +1.

Hope it helps u !!

Answer 2

Explanation:

When five electrons get removed from it, it will acquire positive charge equal to the negative charge which get removed from metal surface. Therefore, positive charge on the metal will be 5e. In terms of coulomb it will be 5 x 1.6 x 10-19 = 8 x 10-19 C.
