where 
is angle between the vectors.
so
squaring both side
10 P2 = (6 + 4
cos)P2
4 = 4cos
SO = 45

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.
