Q)Two beads of equal masses m are attached by a string of length 2^1/2a and are free to movein a smooth circular ring lying in a vertical plane as shown in the figure.Here, a is the radius of yhe ring.Find the tension and acceleration of B just after the beads are released to move.

Sir, I have tried to solve it as in the figure. But I have some doubts as in the image.

this types of doubts are common in nearly all problems. Sir, plz clear my doubts by giving some detail description.

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.
