A satellite is orbiting the earth. It's orbital radius is reduced to half of its initial value then the change in its total energy is

Options

  1. A100 %
  2. B75 %
  3. C50 %
  4. D25 %

Correct answer

A. 100 %

Step-by-step solution

Total energy of satellite revolving around the earth, aligned & E= -G M_t m r & i.e E 1 r & E₂ E₁ = r₁ r₂ & = r₁ r₁ 2 ( Given r₂= r₁ 2 ) & =2 & E₂=2 E₁ & aligned % change in total energy of satellite aligned & = E₂-E₁ E₁ 100 & = 2 E₁-E₁ E₁ 100=100 % aligned
