Answer & Solution

Correct Answer

(D) 0

Step-by-step Solution

Detailed explanation

Recall the formula of torque due to current carrying loop is, ζ=NiABsinθ, here N, i, A & B are a number of turns, current in the coil, area of the coil and magnetic field here θ is the angle between area vector and direction of the magnetic…
