Rahul and Gitika were riding their car along a circular road. The speedometer of the car reads40km/h all throughout the motion. Gitika said they travelled with constant velocity while Rahuldisagreed. Rahul said their displacement was equal to the circumference of path and Gitikadisagreed.a) Do you justify Rahul's disagreement? Why/why not?b) Do you justify Gitika's disagreement? Why/ why not?c) What values of both Rahul and Gitika would you mention? |

Answer» Answer:a) YES I justify Rahul's disagreement As we know that velocity is a vector quantity i.e. it has both magnitude and direction. THOUGH the magnitude of velocity is constant but in a CIRCULAR motion, the direction of motion continuously changes. Therefore we cannot say that the velocity is constant. b) Yes, according to me Gitika's disagreement is equally justified. The displacement is the shortest distance between the INITIAL point of motion/observation and the final point of motion/observation. They travelled to the same point from where they started therefore their displacement MUST be 0 Explanation: |
