A loop of diameter d is placed at a distance 9d from a long straight wire. A current of 20 A flows both in the wire and in the loop, as shown in the figure. The loop feels a torque of 5.0 × 10' -6 'Nm. 9d Wire (a) Is the torque felt by the loop clockwise or counterclockwise? Explain. (b) Find the diameter d of the loop.
