A long, straight wire has a 11.1 ? A current flowing in the positive x -directio

Question

A long, straight wire has a 11.1?A  current flowing in the positive x -direction, as shown in the figure. Close to the wire is a square loop of copper wire that carries a 1.65?A  current in the direction shown. The near side of the loop is d=50.7cm  away from the wire. The length of each side of the square is a=1.31m .

a) Find the net force between the two current-carrying objects.

b) Find the net torque on the loop.
