Binding energy of a revolving satellite at height ' h ' is 3.5 10^8 ~J . Its potential energy is

Options

  1. A-3.5 10^8 ~J
  2. B-7 10^8 ~J
  3. C7 10^8 ~J
  4. D3.5 10^8 ~J

Correct answer

A. -3.5 10^8 ~J

Step-by-step solution

Concept: Binding energy =+ (work done to assemble the planet plus satellite system) BE =+ W We know, potential energy change is related as: U =(- W ) So the potential energy of the system is U =- ( GM _ m r + h )=- W =-3.5 10^8 ~J
