Class 11Physics3-2.Motion in PlaneDynamics of circular Motion (Centrifugal force) and Pendulum and Motion on Curved path
Medium$A$ bob of mass $m$ is whirled in a horizontal plane by means of a string of length $\ell$ with an initial angular speed of $\omega$. The tension in the string is $T$. If the angular speed becomes $2\omega$ while keeping the same radius $\ell$,the tension in the string becomes:
- A$4T$
- B$\frac{T}{4}$
- C$\sqrt{2}T$
- D$T$
