Question

Force of gravitation between two bodies varies with r as

A r

B r²

C 1/r

D 1/r²​

Answer 1

Explanation:

Gravitational force =

r

2

Gm

1

m

2

please follow me

where m

1

and m

2

are the masses of the two bodies .

we observe that m

1

,m

2

and G (gravitational constant) are constants

⟹ Gravitational force is inversely proportional to square of the distance between the two bodies

That is,

G∝

r

2

1

Answer 2

F = G m1 m2 / r sq.

Thus, F is inversely proportional to r sq.
