A) \[\frac{ml{{\omega }^{2}}}{k-\omega m}\]
B) \[\frac{ml{{\omega }^{2}}}{k+m{{\omega }^{2}}}\]
C) \[\frac{ml{{\omega }^{2}}}{k+m\omega }\]
D) \[\frac{ml{{\omega }^{2}}}{k-m{{\omega }^{2}}}\]
Correct Answer: D
Solution :
Sol [d] At elongated position (x), \[{{F}_{radial}}\text{=}mr{{\omega }^{2}}\] \[\therefore kx=m\left( \ell +x \right){{\omega }^{2}}\] \[\therefore x=\frac{m\ell {{\omega }^{2}}}{k-m{{\omega }^{2}}}\]You need to login to perform this action.
