Class 11Physics3-2.Motion in PlaneDynamics of circular Motion (Centrifugal force) and Pendulum and Motion on Curved path
Medium$A$ body of mass $m$ is moving with speed $V$ along a circular path of radius $r$. Now,the speed is reduced to $\frac{V}{2}$ and the radius is increased to $3r$. For this change,the initial centripetal force needs to be:
- Adecreased by $\frac{11}{12}$ times.
- Bincreased by $\frac{11}{12}$ times.
- Cdecreased by $\frac{1}{12}$ times.
- Dincreased by $\frac{1}{12}$ times.
