Question

Derive a relation for acceleration due to gravity. How its value vary with:
(i) mass of the planet (ii) Size of the planet​

Answer 1

Explanation:

Acceleration due to gravity is related Gravitational Potential Energy.

GRAVITATIONAL P. E. =mgh

Where g is constant. It is also related to weight.

Weight is the amount of gravitational pull acting on you

Acceleration due to gravity does not depend on mass

Answer 2

Answer:

in case of acceleration due to gravitation,

g=GM/r²

Explanation:

1.Mass of the planet:g is directly proportional to M.As the mass increases, it also increases.

2.Size of the planet:g is inversely proportional to r².It decrease when the r increases.
