Question

A body is having a charge of 10 C. When it comes in contact with an uncharged body then it looses 1.6 C of charge. Find the number of charges lost.

• A. 1.6
• B. 1.6
• C.
• D. -

Answer 1

The correct option is C

1 electron has a charge of 1.6 $\times$ ${10}^{-19}$ C, so using the unitary method in 1.6 C we will have $\frac{1.6}{(1.6\times {10}^{-19})}$. So, the number of electrons in 1.6 C will be ${10}^{19}$.
