In figure, there is conducting ring having resistance `R` placed in the plane of paper in a uniform magnetic field `B_(0)`. If the rings is rotating in the plane of paper about an axis passing through point `O` and perpendicular to the plane of paper with constant angular speed `omega` in clockwise direction, then

A

Point `A` will be at higher potential than `O`.

B

The potential of point `B` and `C` will be same.

C

The current in ring will be zero.

D

The current in the ring will be `(2B_(0) omega. r^(2))/(R)`.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
The change in magnetic flux is zero, hence the current in the ring will be zero.
