There are two planets and the ratio of radius of the two planets is K but ratio of acceleration due to gravity of both planets is g . What will be the ratio of their escape velocity?

Options

  1. A(K g)^ 1 / 2
  2. B(K g)^ -1 / 2
  3. C(K g)^2
  4. D( Kg )⁻²

Correct answer

A. (K g)^ 1 / 2

Step-by-step solution

aligned v_e & = R g v₁ v₂ & = R₁ R₂ g₁ g₂ & = K g & =(K g)^ 1 / 2 aligned
