A) \[0.2m\]
B) \[0.25m\]
C) \[0.3\text{ }m\]
D) \[0.35m\]
Correct Answer: B
Solution :
When maximum force just exceeds the weight of the body, then weight kept on the system will separate from the piston \[\therefore \] \[mg=m{{\omega }^{2}}y\] \[\Rightarrow \] \[y=\frac{g}{{{\omega }^{2}}}\] Given\[g=9.8\,\,m{{s}^{-2}},\,\,\omega =2\pi \] \[\therefore \] \[y=\frac{9.8}{{{(2\pi )}^{2}}}=0.25m\]You need to login to perform this action.
