A current carrying loop is placed in a uniform magnetic field. The torque acting on the loop does not depend upon
  1. area of loop
  2. number of turns in the loop
  3. shape of the loop
  4. strength of the magnetic field

Solution

$\tau=\mathrm{NiA} \sin \theta$ Torque acting on the loop does not depend upon shape of the loop.
