When some electrons are removed from an uncharged body, it
When an object gets negatively charged by the process of friction, then:
(a) the object loses some electrons (b) the object loses some protons
(c) the object gains some electrons (d) the object gains some protons
When a plastic comb is rubbed with dry hair, the hair get positively charged by friction. In this process:
