Two metallic spheres of same mass are given equal and opposite charges, then :
(1) The mass of positively charged sphere increases(2) The mass of both spheres remains the same(3) The mass of the negatively charged sphere increases(4) The mass of the both spheres increases
Positive charge means we are taking electrons out and negative charge means we are giving the electrons to the body.
SO mass of the negatively charged body is increased.
SO mass of the negatively charged body is increased.
