The intermolecular distance between two H-atoms in a hydrogen molecule is 4 angstrom Then the moment of inertia of the molecule about an axis through centre of mass and Perpendicular to the bond length is approximatly (in kg m2) (1)13.4 x 10^-37 (2)13.4 x 10^-47 (3) 6.7 x 10^-37 . (4) 6.7 x 10^-47

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.
