Question

The number of electrons removed from a body in order to produce positive charge of 5×10 coulomb on it , will be

Answer 1

Answer:

3.125×10²⁰

Explanation:

Removing a certain number of electrons to produce a positive charge is the same as finding how many electrons constitute that charge. So, the number of electrons removed from a body in order to produce positive charge of 5×10 coulomb on it , will be the number of electrons constituting 50 coulomb of charge.

Now, one electron carries 1.6×10¹⁹ coulomb of charge.

So, 6.25×10¹⁸ electrons constitute 1 coulomb of charge.

∴ 3.125×10²⁰ electrons constitute 5×10 or 50 coulombs or charge.
