A uniform ring of mass M and radius R carries a current I (see figure). The ring is suspended using two identical strings OA and OB. There exists a uniform horizontal magnetic field `B_(0)` parallel to the diameter AB of the ring. Calculate tension in the two strings. [Given `theta = 60^(@)`]

Text Solution

Verified by Experts
