Assertion : if the units of force and length are doubled, the unit of energy will be 4 times.
Reason : The unit of energy is independent of the units of force and length

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 a correct explanation of the Assertion.

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
(c )
Here, assertion is true, but reason is false. As Energy = Work = `F xx S` :. When the unit of force and length are doubled the unit of energy will becomes 4 times. Also, unit of energy depends upon force and length.
