(b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
(c ) If Assertion is true but Reason is false.
(d) If Assertion is false but Reason is true.
Assertion If work done by conservative force is negative, then potential energy associated with that force should increase.
Reason This is according to the relation
`DeltaU=-W`
Here, `DeltaU` is change in potential energy and W is work done by conservative force.

Answer

A

Explanation

(a) For conservative forces, `DeltaU=-DeltaW`
where `Delta`U=change in PE
`Delta`W=work done by conservative force.
