Question

a rubber ball loses 20 million electrons.What is the charge on it?

Answer 1

Since, the ball loses the electrons, which are negatively charged, the ball will gain an ewual amount of positive charge.

Hence, the ball will gain charge equal to the magnitude of combined charges of 20 million electrons.

So, the net charge on the ball will be 20000000×q, where q is the magnitude of a charge of electron. I think its 1.6 × 10^-19 coulomb. check it please and substitute it accordingly to obtain the answer.

I hope you understand the concept.
All the best.
