Two identical metallic spheres A and B given equal +ve and -ve charge. Then
Mass of B increases
One metallic sphere A is given a positive charge whereas another identical metallic sphere B of the exactly same mass as of A is given an equal amount of negative charge. Then
Two identical +ve charges are at the ends of a straight line AB. Another identical +ve charge is placed at ‘C’ such that AB=BC. (A, B and C being on the same line). Now the force on ‘A’ will :
