A particle is moving in a circle with uniform speed v. In moving from a point to another diametrically opposite point
Options
(a) The momentum changes by mv
(b) The momentum changes by 2mv
(c) The kinetic energy changes by 1/2 mv²
(d) The kinetic energy changes by mv²
Correct Answer:
The momentum changes by 2mv
Explanation:
The diametrically opposite points, the velocities have same magnitude but opposite directions. Therefore, change in momentum is MV – (- MV) = 2MV.
