Question

how is acceleration due to gravity related to first mass of planets second distance of body from the centre of Earth

Answer 1

1. The acceleration due to gravity is directly proportional to the mass of the planet.

i.e. g ( gravitational acceleration ) ∝ m ( mass of the planet ) 


2. The acceleration due to gravity is inversely proportional to the square of the distance of the body from the center of the earth.

i.e. g ( gravitational acceleration ) ∝ 1 / $r^{2}$ ( distance of the body from the center of the earth )
