Two blocks of masses 2 kg and 4 kg are hanging with the help of massless string passing over an ideal Pulley inside in elevator. The elevator is moving upward with an acceleration g/2. The tension in the string connected between the blocks will beA..... 40 NB..... 60 NC..... 80 ND..... 20 N

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.
