A particle is moving in a circle with uniform speed ' v '. In moving from a point to another diametrically opposite point
Options
- Athe momentum changes by mv
- Bthe momentum changes by 2 mv
- Cthe kinetic energy changes by 1 2 mv ^2
- Dthe kinetic energy changes by mv ^2
Correct answer
B. the momentum changes by 2 mv
Step-by-step solution
At both points, the momentum will be mv, but will be in opposite directions. array ll & P = mv -(- mv ) & P =2 mv array The momentum changes by 2 mv .
