If v_e is escape velocity and v_o is orbital velocity of a satellite for orbit close to the Earth's surface, then these are related by

Options

  1. Av_o= 2 v_e
  2. Bv_o=v_e
  3. Cv_e= 2 v_o
  4. Dv_e= 2 v_o

Correct answer

C. v_e= 2 v_o

Step-by-step solution

Orbital velocity of satellite v_o= G M R ...(i) and escape velocity of satellite v_e= 2 G M R ...(ii) Hence, v_e= 2 v_o
