JEE Main 2022 Physics question
An object of mass 1 kg is taken to a height from the surface of earth which is equal to three times the radius of earth. The gain in potential energy of the object will be [If, g = 10 and radius of earth = 6400 km]
Answer: (1)
Solution
= −GMm/R and = −GMm/4R (at a distance 4R from the centre). The gain is = − =
