A block of mass m welded with a light spring of stiffness k is in equilibrium on an smooth inclined plane with angle of inclination θ. If a variable external force is applied slowly till the spring comes to its relaxed position, find the work done by spring by spring force.

An inclined plane is moving up with constant velocity v. A block kept on incline is at rest. Calculate the work done by gravity friction force
