Answer:

Explanation:
As we know that loop is placed in YZ plane and magnetic field is along x direction
So here net force on the side of the loop which lies along Y axis is given as

here we know that on Y axis z = 0
so B = 0
so we have

now on the opposite side we have z = a
so magnetic field is given as

so force on that side is given as



so net force on the loop is given as
