Two bodies of masses 4 kg and 5kg are acted upon by the same force. If the acceleration of lighter body is 2m//sec^(2) , then the acceleration of the heavier body is:-

On the horizontal surface of a truck (mu=0.6) a block of mass 1 kg is placed. If the truck is accelerating at the rate of 5m//sec^(2) then friction force on the block will be

The blocks are on frictionless inclined ramp and connected by a massless cord. The cord passes over an ideal pully. [g=10m//s^(2)] When to 10 kg block slides down the ramp with acceleration of 2m//s^(2) tension in the crod is closest to :-

A man of mass 80kg pushes box of mass 20kg horizontaly. The man moves the box with a constant acceleration of 2 m//s^(2) but his foot does not slip on the ground. There is no friction between the box and the ground. There is no friction between the box and the ground. whereas there is sufficient friction between the man's foot and the ground to prevent him from slipping. Assertion:- The force applied by the man on the box is equal and opposite to the force applied by the force applid by the box on the man. Reason:- Friction force applied by the ground on the man is 200N.
