A body is negatively charged, if it loses electrons.

A body is positively charged. It has

The body is positively charged. Then its mass effectively.

(ii) Choose the best appropriate explanation from the following (a) To give the sphere a negative charge, we must give it more electrons and this will increase its mass. (b) A positive charge increases the sphere's mass and a negative charge decreases its mass, (c) Charge is conserved, therefore the mass of the object will remain the same.

A balloon gets negatively charged by rubbing ceilings of a wall. Does this mean that the wall is positively charged? Why does the balloon eventually fall?
