A) \[{{\pi }^{2}}m/{{s}^{2}}\]
B) \[2{{\pi }^{2}}m/{{s}^{2}}\]
C) \[4{{\pi }^{2}}m/{{s}^{2}}\]
D) \[8\pi \,m/{{s}^{2}}\]
Correct Answer: C
Solution :
Centripetal acceleration\[=4{{\pi }^{2}}{{n}^{2}}r=4{{\pi }^{2}}{{\left( \frac{1}{2} \right)}^{2}}\times 4=4{{\pi }^{2}}\]You need to login to perform this action.
