A) \[1.88\,\,m/s,\,\,35.5\,\,m/{{s}^{2}},\,\,35.5\,\,N\]
B) \[2.88\,\,m/s,\,\,45.5\,\,m/{{s}^{2}},\,\,45.5\,\,N\]
C) \[3.88\,\,m/s,\,\,55.5\,\,m/{{s}^{2}},\,\,55.5\,\,N\]
D) None of these
Correct Answer: A
Solution :
Linear velocity, \[v=\omega r=2\pi nr=2\times 3.14\times 3\times 0.1=1.88\,m/s\] Acceleration, \[a={{\omega }^{2}}r={{(6\pi )}^{2}}\times 0.1=35.5\,m/{{s}^{2}}\] Tension in string, \[T=m{{\omega }^{2}}r=1\times {{(6\pi )}^{2}}\times 0.1=35.5\,N\]You need to login to perform this action.
