A uniform chain of length l and mass m overhangs a smooth table with its two third part lying on the table. Find the kinetic energy of the chain as it completely slips off the table.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
With respect to the top of the table, the initial potential energy of the chain, 
of the chain lying on the table + PE of the over hanging part of the chain
PE of chain at the instant of slip,
Since only gravity is acting on the chain, we have
Since
