Q.

A single turn current loop in the shape of a right angle triangle with sides 5 cm, 12 cm, 13 cm is carrying a current of 2 A. The loop is in a uniform magnetic field of magnitude 0.75 T whose direction is parallel to the current in the 13 cm side of the loop. The magnitude of the magnetic force x on the 5 cm side will be x130N. The value of x is _______.              [2023]


Ans.

(9)

Force on 5 cm side is

|F|=ILBsinθ

       =(2)(5×10-2)×34×1213=9130N

So, x=9
