The mass of a planet is 1 10 th that of the earth and its diameter is half that of the earth. The acceleration due to gravity on that planet is:

Options

  1. A9.8 ~m ~s ⁻²
  2. B4.9 ~m ~s ⁻²
  3. C3.92 ~m ~s ⁻²
  4. D19.6 ~m ~s ⁻²

Correct answer

C. 3.92 ~m ~s ⁻²

Step-by-step solution

aligned g^ = G M^ R^2 & = G M 10 ( R 2 )^2 & = 4 10 G M R^2 =0.4 9.8 & =3.92 ~m ~s ⁻² aligned
