h=ut1−12gt21−h=ut1−12gt12--------(i)h=ut2+12h=ut2+12gt22gt22--------(ii)Where h is a positive number. Multiplying (i) by t2t2 and (ii) by t1t1 we get,h(t1+t2)=12=12h(t1+t2)=12=12gt1t2(t1+t2)gt1t2(t1+t2)-----------(iii)y=12y=12gt2gt2---------(iv)From (iii) and (iv)t=t1t2−−−√t=t1t2

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.
