An artificial satellite moving in a circular orbit around the earth has a total (kinetic + potential) energy E₀ , its potential energy is

Options

  1. A-E₀
  2. B1.5 E₀
  3. C2 E₀
  4. DE₀

Correct answer

C. 2 E₀

Step-by-step solution

Total energy, E₀=- G M m 2 r (i) and potential energy, V=- G M m r (ii) From Eqs. (i) and (ii), we get =2 E₀
