A) \[20\times {{10}^{8}}m/{{\sec }^{2}}\]
B) \[8\times {{10}^{5}}m/{{\sec }^{2}}\]
C) \[120\times {{10}^{5}}m/{{\sec }^{2}}\]
D) \[4\times {{10}^{8}}m/{{\sec }^{2}}\]
Correct Answer: B
Solution :
\[a={{\omega }^{2}}r=4{{\pi }^{2}}{{n}^{2}}r=4{{\pi }^{2}}\times {{1}^{2}}\times 20\times {{10}^{3}}\] \ a=\[8\times {{10}^{5}}\ m/{{\sec }^{2}}\]You need to login to perform this action.
