Question

three equal masses m are placed at three vertices of equilateral triangle of side if the gravitational force exerted by this system on another particle of mass m is placed at the centroid of triangle

Answer 1

Answer:

Force in OB=As equal and opposite forces cancel each other

Force in OC=

[(

3

/2)a]

2

Gm

2

=

3a

2

4Gm

2

So net gravitational force on m=

3a

2

4Gm

2
