A block is tied to the middle of a string and suspended from one end as shown in figure. Here M is the block and O is the point of suspension. If you give a sharp jerk at J, the string will break (a)below the point (b)from above the block (c)at the point J itself (d)none of these. Explain..... In the above question , if we increase the pull at J gradually , the string will break. (a)Below the block (b)from above the block (c)at point J itself (d)none of these

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.
