Q.A square loop of side $a$ carrying current $I$ is kept at a distance $a$ from an infinitely long straight wire carrying current $I$ . The net force on the loop is

\dfrac{\mu_0 I^2}{2\pi}

toward the wire

\dfrac{\mu_0 I^2}{\pi}

toward the wire

\dfrac{\mu_0 I^2}{2\pi}

away from the wire

zero

The correct solution involves applying the fundamental concept to derive the final value step by step...
