Dear student
U sin(theta ) = 0 at the highest point
either U = 0 (which is not the case )
or sin(theta)= 0 (only possibility)
U sin(theta ) = 0 at the highest point
either U = 0 (which is not the case )
or sin(theta)= 0 (only possibility)

Angle at highest point in projection is zero. Because, it is parallel to horizontal . Sin(theta) =0
Therefore, (theta) =zero (0)

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.
