Question

Two bodies of mass 1 kg and 2 kg are separated by a
distance of 1m on the surface of earth, then the
gravitational force between these bodies is
4X6.67X10-11 N
3X6.67X10-11 N.
2X6.67X10-11 N
1X6.67X10-11 N

Answer 1

Answer:

6.67×10 −11 N

Explanation:

Given : m1 =m2 =1 kg, r=1 m

Force of gravitation F= r 2Gm 1 m 2

F= 1/ 2 6.67×10 −11/ ×1×1

=6.67×10 −11 N
