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