A) 3 cm
B) 4.2 cm
C) 5.8 cm
D) 6 cm
Correct Answer: B
Solution :
If at any instant displacement is y then it is given that \[U=\frac{1}{2}\times E\] Þ \[\frac{1}{2}m{{\omega }^{2}}{{y}^{2}}=\frac{1}{2}\times \left( \frac{1}{2}m{{\omega }^{2}}{{a}^{2}} \right)\] Þ \[y=\frac{a}{\sqrt{2}}=\frac{6}{\sqrt{2}}=4.2\,cm\]You need to login to perform this action.
