There is a simple formulae to find the Radius of trajectory in projjectile motion.
And for that U must know the eqn. of trajectory motion.
that is
y = xtanthetha – gx^2/2u^2*cos^2thetha.
find dy/dx and also its double derivative and then put it in the below formulae.
R = (1 + (dy/dx)^2)^3/2/|d^2y/dx^2|

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.
