p { margin-bottom: 0.25cm; line-height: 120%; }

Assuming that we are not taking help of friction for negotiating circular path, the angle of banking for safe turning is given by the equation . Substituting the values v = 72 km/hr = 20 m/s, R = 50 m and g = 10 m/s², we get

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.
