Two wires A & B are carrying currents I_1 & I_2 as shown in the figure.The separation between them is d. A third wire C carrying a current I is to be kept parallel to them at a distance x from A such that the net force acting on its is zero.The possible values of x are :

An electric dipole is held in a uniform electric field. Straight the net force acting on it is zero.

a) In a frame of reference S( though the net force is zero, the net acceleration is not zero. b) In a frame of reference S_2 though the net force is not zero, the net acceleration is zero. c) In a frame of reference S_3 the net acceleration is zero whenever the net force is zero.
