Dear vardana
ANGLE BTW (i+j+k) and (i+j) is x
cosx =(i+j+k).(i+j)/|i+j+k||i+j|
=2/√3 √2
=√2/√3
secx =√3/√2
2sec2x =3

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.
