- (please type answer)Students noted that their friend's hair standing up when he removed the hat from the head. Their science teacher asked them to explain the reason based on your electrostatics knowledge. Which will be the best answer? O A. There is thermal energy produced and that caused kinetic energy to the hair. O B. Chemical reactions make the hair more rigid. O C. Hair gains electrons when the hat is removed and so hair is attracted to the surrounding air. D. The hair loses electrons causing the them to repel each other. Same charges repel.How do the plates acquire a charge after the voltage is applied to them? Please help. I don't understand
