The gravtiatation force on the a single particle is Gm2/a2 + Gm2/a2 + Gm2/2a2 = 5Gm2/2a2

= 5Gm2/2a2= root(2)mv2/a (Centripetal force)

= (5Gm/2a(root(2)))^1/2

Sorry for my mistake,

The gravtiatation force on the a single particle is Gm2root(2)/a2 + Gm2/2a= Gm2(2root(2)+1)/2a2

= Gm2(2root(2)+1)/2a2= root(2)mv2/a (Centripetal force)

= (Gm(1+1/2(root(2))/a)^1/2

Daer Aashish,

The gravtiatation force on the a single particle is Gm2root(2)/a2 + Gm2/2a= Gm2(2root(2)+1)/2a2

= Gm2(2root(2)+1)/2a2= root(2)mv2/a (Centripetal force)

= (Gm(1+1/2(root(2))/a)^1/2

Best Of luck
