A uniform chain has a mass ' ' and length '. It is held on a frictionless table with one-sisth of its length hanging over the edge. The work done in just pulling the hanging part back on the table is:
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Work done in pulling the hanging par of chain on table is equal to gain in potential energy, W=Mgh Mass of hanging part which is 16th of the total length, given that mass of chain is m is m6. Centre of mass is located at a distance l12 from the table.…
