Dear Student
Your question seems to be unclear or incomplete . Please provide us complete and clear question
Besides , the angle between horizontal and vertical axis is 900.So, we use cos 900
Thanks

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.
