Question

What effect do mass and distance have on the force of gravity?

Answer 1

Let Gravity be G.

Then G=$\frac{m1m2}{r^2}$

Thus G∝m1m2.

Hence if mass of a body is increased twice then its gravity becomes twice as well.

And:-

G∝$\frac{1}{r^2}$

Hence if distance between them is decreased by twice then gravity decreases by:-

$\frac{1}{2^2}$

or, $\frac{1}{4}$

Thanks

Hope it helped.

Answer 2

g= m1 m2/ r^2

g is

directly proportional to mass product

and

inversely proportional to r^2
