A chain of mass of uniform density is kept above the surface of the Earth in the form of a quarter circle of radius as shown in the figure. Find the total potential energy of the chain at this position, in joules, upto 2 decimal places.
There is no air resistance.
Potential energy at the surface of the Earth
This problem is not original, but the graph is plotted and edited by me.
I will be very glad and grateful if you post a solution.
