Assertion: Cyclotron is a device which is used to accelerate the position ions.
Reason: Cyclotron frequency depends upon the velocity.

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

The correct Answer is:
C
Cyclotron is suitable for accelerating heavy charged particles such as proton. `alpha`-particle and positive ions. In a cyclotron, the positive ions cross agin and again the same alternating (ration frequency) electric filed. Cyclotron is also known as magnetic resonance accelerator. Cyclotron frequency is given by
`v=1/T=(Bq)/(2pim)` . It is obvious that cyclotron frequency does not depend upon velocity of charged particle.
