Question

113. If different planets have the same density
but different radii then the acceleration
due to gravity (g) on the surface of the
planet will depends on its radius (R) as​

Answer 1

Explanation:

GM = R^2 g or

G(4/3 πR^2 ρ) = R^2g or

g = (4/3 πGρ) G.

hence acceleration due to gravity is directly proportional to radius
