A uniform chain of length L and mass M is lying on a smooth table and one third of its length is hanging vertically down over the edge of the table. If g is acceleration due to gravity, work required to pull the hanging part on to the table is
- \(\text { MgL }\)
- \(\frac{M g L}{3}\)
- \(\frac{M g L}{9}\)
- \(\frac{M g L}{18}\)
Answer
(D) M g L 18
