Name the forces which are in equilibrium in each of the following situations :(a) a book resting on a table. Whenever there is change is momentum of the given body there is change of the velocity hence acceleration .According to the Newton’s 1 st law of motion, the change in motion is produced by the external force .so, change in momentum and force are interrelated.
