You are to examine these two statements carefully and decide if the Assertion A and Reason R are individually true and if so, whether the reason is a correct explanation of the assertion. Select your answers to these items using codes given below. Assertion: If an object travels in such away that it comes back to the starting position, then the displacement is zero but, the distance travelled is not zero. Reason: The displacement is the shortest distance between the initial and final position of the body whereas, distance is the actual path length covered by an object.
