A hard rubber comb is pulled through a student's hair, and acquires a negative electric charge. This must mean that ---. 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

the comb is taking electrons from the hair

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
