The value of quantity G in the law of gravitation

(a) depends on mass of earth only

(b) depends on radius of earth only

(c) depends on both mass and radius of the earth

(d) is independent of mass and radius of the earth

D

Sol. Gravitational force is a fundamental force, and it comes because of the property of mass.

According to Newton’s gravitational law, any two bodies having mass will attract each other by gravitational force.

According to the universal law of gravitation, gravitational force is proportional to the product of masses and inversely proportional to the square of distance between them.

Gravitational force is given as:

F= \frac{Gm_{1}m_{2}}{r^{2}}

G is the universal gravitational constant, which does not depend on any other physical quantity.

G is independent of mass and radius of the earth.

The correct answer of this question is option D.
