Question 2 options:


the comb is electrically connected to the ground



the comb is taking electrons from the hair



the hair is taking protons from the comb



the comb is creating electrons

Answer 1

the comb is taking electrons from the hair

Step-by-step explanation:

As given,

A hard rubber comb acquires a negative electric charge.

Before rubbing,

The comb and the hair are electrically neutral

So, when we rub the comb with the hair , the electrons are transferred to the comb and the hair losses its negative charge and ended up with the positive charge.

So,

The correct option is - the comb is taking electrons from the hair
