Calculate the resultant gravitational field at point P situated in between Sun and Earth on the line joining them while the distance of P from the Earth is the same as that of the moon from the Earth. Given- Massof Earth=5.97 *10^24 kg, distance between Earth and Moon=3.84*10^8m, distance between Earth and Sun=1.496*10^11m.

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.
