A satellite moving round the earth in a circular orbit has kinetic energy ' E '. Then, the minimum amount of energy to be added so that it escapes from the earth.

Options

  1. AE 4
  2. BE
  3. CE 2
  4. D2 E

Correct answer

B. E

Step-by-step solution

By conservation of energy, aligned & U _ i + K _ i + E = U _ + K _ & -2 ~K _ i + K _ i + E =0 & E = K _ i = E aligned
