If R is the radius of the earth and g is the acceleration due to gravity on the earth surface. Then the mean density of the earth will be

Options

  1. A3 g 4 R G
  2. B4 G 3 g R
  3. CR G 12 g
  4. D3 R 4 g G

Correct answer

A. 3 g 4 R G

Step-by-step solution

Acceleration due to gravity on the earth surface g= G M R^2 aligned & g=G 4 3 R^3 R^2 & g=G 4 3 R & = 3 g 4 G R aligned
