A body revolves with constant speed v in a circularpath of radius r. The magnitude of its averageacceleration during motion between two points indiametrically opposite direction is41.2(1) Zero222r |

Answer» Average acceleration is change in velocity by either change in its magnitude or change in its direction. But here for a uniform circular motion magnitude being constant (speed) direction changes which causes change in acceleration and by definition from NCERT acceleration is change in velocity during the course of overall interval. Therefore following ans should be the quick answer for the given question : Here v1 and v2 are two velocities say at point P and Q diametrically opposite points. |
