A semicircular ring is present in the uniform magnetic field. Magnetic field is perpendicular to loop of ring. Assertion: Force `vec(F)` on each element of ring is different
Reason: Net force on ring must be perpendicular to magnetic field.

A

If both the assertion and reason are true and reason is a true explantion of the assertion.

B

If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts
