DIRECTIONS: The questions in this segment consists of two statements, one labelled as ?Assertion A? and the other labelled as ?Reason R?. 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.
