Question

.If the force between two masses M and m which are kept at a distance R apart in the space is F. Then what should be the force between them for the same arrangement in water?​

Answer 1

Answer:

According to Sir Newton's gravitational law the magnitude of gravitational force F between objects of mass m

1

and m

2

separated by a distance R is given by

F=G

R

2

m

1

m

2

eq1

now if the distance between them is doubled 2R then the gravitational force will be

F

=G

(2R)

2

m

1

m

2

=G

4R

2

m

1

m

2

now by using eq1

F

=F/4

mark me as brainest answer
