MHT CET 2023 Physics question
The ratio of energy required to raise a satellite to a height 'h' above the earth's surface to that required to put it into the orbit at the same height is (R = radius of earth)
Answer: (A)
Solution
Energy to raise the satellite (mass ) to height is the increase in potential energy: (using ). Energy to put it in orbit at that height also includes its orbital kinetic energy , so
