A) \[2\pi \,\,\times \,\,{{10}^{-}}^{7}\]
B) \[2\pi \,\,\times \,\,{{10}^{-}}^{5}\]
C) \[0.5\]
D) \[\,50\]
Correct Answer: A
Solution :
\[M=mL\] \[={{10}^{-}}^{3}\,\,\times \,\,0.1\] \[={{10}^{-4}}\] \[Torque\,\tau \,\,=\,\,MB\text{ }\sin 30{}^\circ \] \[={{10}^{-4}}\times 4\pi \times {{10}^{-3}}\times \frac{1}{2}\] \[=\,\,\,2\pi \times {{10}^{-}}^{7}\,N-m\]You need to login to perform this action.
