A) \[{{\pi }^{2}}\]
B) \[8{{\pi }^{2}}\]
C) \[4{{\pi }^{2}}\]
D) \[2{{\pi }^{2}}\]
Correct Answer: C
Solution :
Since \[n=2\], \[\omega =2\pi \times 2=4\pi \,rad/{{s}^{2}}\] So acceleration \[={{\omega }^{2}}r\]\[={{(4\pi )}^{2}}\times \frac{25}{100}\,m/{{s}^{2}}=4{{\pi }^{2}}\]You need to login to perform this action.
