Question

what is G ?write its value and unit ? on what factors does a value of g depends?

Answer 1

G is a value which is constant on whole earth.

Value of G is 6.67 ×10^-11 Nm^2/kg^2.

Also known as universal gravitational constant .

Answer 2

G is gravitational constant

Value is 9.8 m/s²

Unit is m/s²

Factors:

g=GM/R², where G is gravitational constant, M is the mass of the planet, R is the distance of the point of consideration from the center of the planet since G is constant g depends on mass of the planet and the location
