Question

What is the Gravitation force between two bodies of same mass , and radius , if they are touching each other

Answer 1

Gravitational Force = Gm1m2/r^2

In this case ;
m1 = m2
r = Radius of m1 + Radius of m2
r = 2r

Gravitational Force
= G×m×m/(2r)^2
= (4 Gm^2)/r^2

Answer 2

Explanation:

Gravitational Force = Gm1m2/r^2

In this case ;

m1 = m2

r = Radius of m1 + Radius of m2

r = 2r

Gravitational Force

= G×m×m/(2r)^2

= (4 Gm^2)/r^2
