Answer 2

Answer:

Explanation:

saiadityas answer is partially correct, since he didn’t chose the correct direction, because the currents are flowing in the same direction, there will be attractive force and not repulsive,hence, changing the direction of f2 and f6, thereby making the direction as towards right, kindly notice.
