Question

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. A. 9.8 ~m ~s ^ -2
  2. B. 4.9 ~m ~s ^ -2
  3. C. 3.92 ~m ~s ^ -2
  4. D. 19.6 ~m ~s ^ -2

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
