Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

method 2 is actually correct, because in this you have taken the formula of general gravitational potential. whereas in method 1, your PE=mgh, this is applied only when you are considering motion near to surface of earth. But R/4, is actually comparable to R and hence mgh can't be used. extra Note: mgh, can actually be derived from the general gravitational potential formula.
