Question

A rectangular loop of sides 20 cm and 10 cm carries a current of 5.0 A. A uniform magnetic field of magnitude 2 T exists parallel to the longer side of the loop. The torque acting on the loop is

Answer 1

Answer:

$torque \: = binasin \beta \\ torque \: = 2 \times 5 \times (0.2 \times 0.1) \times 1 \\ torque = 0.2$
