Assertion: Cyclotron does not accelerate.
Reason: Mass of the electron is very small.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is the correct explanation of assertion.

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Cyclotron is not suitable for accelerating electrons. Due to the small mass, the speed of electrosn increaes rapdily. Likewise, due to quick relativistic variation in their mass, the electrons get out of step with the oscillating electric field.
