Solution

## The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for AssertionIf work done by conservative forces is positive, then →F⋅→s>0.Thus the one component of force is along the direction of displacement. Thus the speed of the objects tends to increase as the force continues to be applied on the object. Hence assertion is correct.Since the total energy of a body is constant, the potential energy decreases with increase in kinetic energy. However the Reason is not correct explanation of Assertion as in case of a block being pushed on a horizontal frictionless surface..
