Two particles start together from a point O & slide down straight smooth wires inclined at 30° & 60° to the vertical plane & on the same side of vertical through . the relative acceleration of second with respect to first will be in magnitude:

a) g/2

b) √3g/2

c) g/√3

d) g

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.
