the volume of water drawn in 10 min is :
A string with one end fixed on a rigid wall, passing over a fixed frictionless pulley at a distance of 2m from the wall, has a point mass M of 2kg attached to it at a distance of 1m from the wall. A mass m of 0.5kg is attached to the free end. The system is initially held at rest so that the stirng is horizontal between wall and pulley and vertical beyond the pulley as shown in figure.
