Question

The gravitational force produced between any two objects kept 2.5×10^4km apart is 580N.At what distance should they kept so that the gravitational force becomes half.

Answer 1

Answer:

The gravitational force is given as,

F=G

R

2

mM

So the distance between the two objects so that the force is halved is given as,

100=G

R

1

2

mM

50=G

R

2

2

mM

On dividing the above two equations we get

R

2

=

2

R
