Assertion : A kinetic energy of a body...

Assertion : A kinetic energy of a body is quadrupled, when its velocity is doubled. Reason : Kinetic energy is proportional to square of velocity

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

`K = (1)/(2)m v^(2) therefore K prop v^(2)`
If velocity is doubled then K.E. will be quadrupled.
