root(a2 +b2 +c2) =1
a2+b2+c2=1
0.62 + 0.82 + c2 =1
0.36 + 0.64+ c2 =1
1 +c2 =1
c2 =0
thus, c =0

since, a i^ + bj^ + ck^ is a unit vector,
root(a2 +b2 +c2) =1
a2+b2+c2=1
0.62 + 0.82 + c2 =1
0.36 + 0.64+ c2 =1
1 +c2 =1
c2 =0
thus, c =0jk

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
