Question

Assertion: Cyclotron is a device which is used to accelerate the positive ion. 

Reason: Cyclotron frequency depends upon the velocity.

(a) If both assertion and reason are true and the reason in the correct explanation of the assertion.

 (b) If both assertion and reason are true but the reason is not correct explanation of the assertion.

(c) If assertion is true but reason is false.

(d) If the assertion and reason both are false.

(e) If assertion is false but reason is true.

Answer 1

(c) If assertion is true but reason is false. 

Explanation: Cyclotron is utilised to accelerate the positive ion. And cyclotron frequency is given by v = \(\frac{Be}{2πm}\) . It means cyclotron frequency doesn’t depends upon velocity.
