| Oct 8, 2019 at 13:00 | comment | added | Arun Arora | Hello Maco Ocram, actually I am a littlle confused with the concept of definite sized bodies being assumed as point object. One school of thought says a body can be assumed as a point object when it travels distance much greater than its size. Another says a definite sized body can be assumed to be a point object when it is in such motion that each of its particles are under same displacement, velocity and acceleration. In above question, nothing can be said about distance travelled. Though in option 1 and 2 each particle is under same acceleration and velocity. | |

What is your specific difficulty with the question? | |
