Question

A glass rod rubbed with silk acquires a charge +1.6 X 10 - 120. What is the charge on the silk?​

Answer 1

Answer:

-1.6*10^-12

Explanation:

The charges lost by the glass (10^7 electrons) are gained by the silk cloth

Answer 2

The charge acquired on the silk is $-1.6\times 10^{-12}\ C$.

Explanation:

We have,

A glass rod rubbed with silk acquires a charge of $+1.6\times 10^{-12}\ C$. We need to find the charge on the silk. We know that net charge on the system of two rubbed bodies is zero. There are equal amount of opposite charges balance  each other.

When a glass rod is rubbed with silk, opposite charges gets induced in it. Hence, the charge acquired on the silk is $-1.6\times 10^{-12}\ C$.
