Answer:

Explanation:
We are given that



Current,I=

We have to find the maximum charge of the capacitor.
Charge on the capacitor,

....(1)

....(2)
Equation (2) divided by equation (1)




Hence, the maximum charge of the capacitor=
Answer:
Explanation:
Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle
torque is zero as , centripetal force passes through axis of rotation that is center.
So work done by centripetal force = 0
So work done by tension on M = 0
I think that numbers one, three, and four are true
