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 :
A
`x=(I_1/(I_1-I_2))d` and `x=I_2/((I_1+I_2))d`
B
`x=(I_1/(I_1+I_2))d` and `x=I_2/((I_1-I_2))d`
C
`x=(I_1/(I_1+I_2))d` and `x=I_2/((I_1-I_2))d`
D
`x=(I_1d)/((I_1-I_2))`
