A metallic square loop PQRS is moving in its own plane with velocity v in a uniform magnetic field perpendicular to its plane as shown in Fig. If `V_(P), V_(Q), V_(R) and V_(S)` are the potentials of points P, Q, R and S then which of the following is an incorrect statement?

A

`V_(P)=V_(Q)`

B

`V_(P)gtV_(S)`

C

`V_(P)gtV_(R)`

D

`V_(S)=V_(R)`

Text Solution

Verified by Experts

The correct Answer is:
D
Since entire loop is in magnetic field so no net emf will be induced in the loop, hence no current will flow in the loop.
so, `V_(P)=V_(Q), V_(S)=V_(R), V_(P)gtV_(S), V_(P)`
`gtV_(R), V_(Q)gtV_(R`).
