(d)

Here,

The gravitational force on mass  at  due to mass

 at  is  along

The gravitational force on mass  at  due to mass

 at  is  along

The gravitational force on mass  at  due to mass

 at  is  along

Resolve forces  and  into two rectangular components

 and  are equal in magnitude of equal and opposite direction
