Question

how does the force of gravitation between two objects change when the distance between them is reduced to half​

Answer 1

F=G(m1m2)/r^2

therfore F is inversely proportional to r squared

let F1=F

r1=r

r2=r/2

F2=?

F1/F2=(r2)^2/(r1)^2

F/F2=(r/2)^2/(r)^2

F/F2=1/4

F2=4F

thus if distance between them is reduced to 1/2 then gravitational force becomes 4 times

Answer 2

Answer:

According to the universal law of gravitation, gravitational force (F) acting between

two objects is inversely proportional to the square of the distance (r)

between them, i.e.,

If distance r becomes r/2, then the gravitational force will

be proportional to

Hence, if the distance is reduced to half, then the gravitational force becomes four

times larger than the previous value.
