The gravitational potential energy of a body on the surface of the earth is E. If the body is taken from the surface of the earth to a height equal to 150 % of the radius of the earth, its gravitational potential energy is

Options

  1. A0.4 E
  2. B0.2 E
  3. C0.6 E
  4. D0.3 E

Correct answer

A. 0.4 E

Step-by-step solution

E = - GMm R , h =1.5 R aligned & R ^ =( R + h )=( R +1.5 R )=2.5 R & E ^ =- GMm R ^ =- GMm 2.5 R = 1 2.5 (- GMm R ) & E ^ = E 2.5 =0.4 E aligned
