You comb your hair and the comb becomes negatively charged. strictly speaking, how will the mass of your hair change? a. it wil increase b. it will decrease c. it wil not change

C. it will not change.

Explanation:

While combing, the rubbing of the comb with the hair, transfer of electron takes place from the hair to the comb and the comb becomes negatively charged. But, this transfer of electron does not make any considerable change in the mass of the hair. This is because the mass of an electron is highly negligible. Now, neglecting the mass of an electron, the transfer of the electrons from the hair to the comb makes charging of the comb, but no loss of mass in the hair. So, the mass of hair will no change.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
