Question

what is the force between two spheres weighing 20 kg each and placed 50 cm apart

Answer 1

there is gravitational force present between them

Answer 2

The answer to this question is following:

m₁=m₂=20kg

r=50cm or 0.5m

G= 6.67 x 10⁻¹¹

formula of force  

F= G m₁m₂/r²

=6.67 x 10⁻¹¹ x 20 x 20/ 0.5

=1.067 x 10⁻⁷
