Assertion: Speed of a particle moving in...

Assertion: Speed of a particle moving in a circle varies with time as, `u=(4t-12)` . Such type of circular motion is not possible.
Reason: Speed cannot change linearly with time.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true, true but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
For `tlt3sec` , speed is negative which is not possible.,
