Question

Three uniform spheres of mass M and radius R each are kept in such a way that each touches the other two. The magnitude of the gravitational force on any of the sphere due to the other two sphere is​

Answer 1

3^(1÷2)GM^2/(4(R^2))

Answer 2

Answer:

f1=f2=f3

Gm^[2/4r]^2 = 4gm^/3r

fr=2fcosn/2 = root3 Gm^2/4R^2
