Class 11Physics3-2.Motion in PlaneDynamics of circular Motion (Centrifugal force) and Pendulum and Motion on Curved path
Medium$A$ mass $m$ is attached to one end of a spring with spring constant $k$ and natural length $l$. The system is rotated in a horizontal plane with an angular velocity $\omega$. What is the extension in the length of the spring?
- A$\frac{m\omega^2 l}{k}$
- B$\frac{m\omega^2 l}{k - m\omega^2}$
- C$\frac{m\omega^2 l}{k + m\omega^2}$
- DNone of these
