Homework Statement
A charge Q is uniformly distributed on the ring which is free to rotate about a light horizontal rod. The rod is suspended by light inextensible strings and a magnetic field B is applied as shown in the figure. The initial tensions in the strings are To. If the breaking strength of each string is 3To/2, find the maximum angular velocity w with which the wheel can be rotated.
The Attempt at a Solution
I want to clear some doubts before proceeding with the solution-
It is given that the ring is free to rotate about the rod. Is the ring attached to the rod by another rod? If yes then does the former rod rotate with it?
What causes the tension to change in the strings?
