Question

4
Two identical bar magnets, each of same length
and magnetic moment, one bent into a
semicircular are placed as shown. If the angle
made by the resultant magnetic moment with
the magnetic axis of semicircular arc is theta, then
(1) tan theta = 1
(2) tan theta = 1.57
(3) tan theta = 0.63 (4) tan theta = 0.5​

Answer 1

Explanation:

(4) tan theta = 0.5...........

Answer 2

Explanation:

tan theta = 0.5

Hence, option (4) is the correct answer.
