Assertion: A body of mass `1 kg` is making `1 rps` in a circle of radius `1 m`. Centrifugal force acting on it is `4 pi^2 N`.
Reason: Centrifugal force is given by `F = (mv^2)/( r)`.

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
A

`f = 1rps, r= 1m, m = 1kg`
`F = m omega^(2)r = 1(2pi)^(2)1 = 4pi^(2)N`
