A conducting rod is moved with a constant velocity v in a magnetic field. A potential difference appears across the two ends

A

if `vecupsilon||vecl`

B

if `vecupsilon||vecB`

C

if `vecl||vecB`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
if`vecupsilon||vecl` or `vecupsilon||vecB`then `(dphi)/(dt)` is zero.Hence potential difference is zero.
