Let us consider the situation given in the figure. Let r is the radius of turn which you have to take. N1 and N2 are normal reactions mg the weight and F1, F2 the frictional forces on the inside and outside wheels.
So, (N1 + N2) = mg ......... (i)
Thus, F1 + F2 = μ(N1 + N2) = μgm ......... (ii)
This must be greater than or equal to the centripetal force required.
or, v
or, Vmax = √μrg

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.
