A) 4 rad/s
B) 8 rad/s
C) 1 rad/s
D) 2 rad/s
Correct Answer: A
Solution :
Breaking - Strength == Tension in the wire \[=mr\,{{\omega }^{2}}\] \[4.8\times {{10}^{7}}\times {{10}^{-6}}=10\times 0.3\times {{\omega }^{2}}\] \[{{\omega }^{2}}=\frac{48}{0.3\times 10}=16\] \[\omega =4\,rad/s\]You need to login to perform this action.
