Rahul and Rohan are climbing two different hills of the same height but different inclinations. Rahul's hill is making less angle with horizontal than that of Rohit's. Who is doing more work in climbing to the top? (Assume they have equal mass)
Depends on the speed of climbing
Work done = Change in their potential energy.
Let their masses be m1&m2 respectively.
Work done by Rahul = Change in his potential energy = m1gH
Work done by Rohit = Change in his potential energy = m2gH
Hence, work done by both will be same.
