According to Earnshaw's theorem, A freely movable charge cannot exist in stable equilibrium in free space under influence of electrostatic fields alone. But when a positive charge is placed in the middle of two negative charge of same strength, then if we displace the positive charge slightly the positive charge oscillates about the middle point. So the positive charge is in stable equilibrium. Does it contradict the Earnshaw's theorem. ?
