a particle of mass m1 is fastened to one end of a string and another one of mass m2 to the middle point,the other end of the string being fastened to a fixed point on a smooth horizontal table the particles are then projected, so that the two portions of the are always in the same staight line and describe horizontal circles. Find he ratio of tensions in the two parts of the string

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.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
