A) \[144\,{{\pi }^{2}}\]
B) \[188\,{{\pi }^{2}}\]
C) \[288\,{{\pi }^{2}}\]
D) None of these
Correct Answer: C
Solution :
[c] Max. force = mass \[\times \] max. acceleration \[=m4\,{{\pi }^{2}}\,{{v}^{2}}a=1\times 4\times {{\pi }^{2}}\times {{(60)}^{2}}\times 0.02\] \[=288\,{{\pi }^{2}}\]You need to login to perform this action.
