Question

Energy required to move a body of mass m from an orbit of radius 2R to 3R is [AIEEE 2002] ​

Answer 1

Answer:

Energy Required = (Final Potential - Initial Potential)m

Energy Required = -GMm/3R - (-GMm/2R)

= GMm/6R

Answer 2

Explanation:- Gravitational potential energy of body will be E = - GMm/r

Where M = mass of earth

• m = mass of the body
• R = radius of earth

• as r = 2R

E ₁ = - GMm/(2R)

• as r = 3R₁

E₂ = - GMm/(3R)

Energy required to move of mass m from an orbit of radius 2R to 3R is

∆E = GMm/R [1/2 -1/3] = GMm/6R Answer
