What will be the nature of force between B and C if A and B repel each other while A and C attract each other?
can't predict
neutral
repulsive
attractive
The force between B and C is attractive in nature as the sign of charges A and B is same but that of C is opposite.
A boy while playing with two magnets got familiar with their attractive and repulsive properties. He observed the magnets attracting and repelling each other from a distance. From this we can conclude that
Two point charges 3×10−6C and 8×10−6C repel each other by a force of 6×10−3N. If each of them is given an additional charge −6×106C, the force between them will be
