A) \[\frac{3v}{4l}\], anti-clockwise
B) \[\frac{4v}{3l},\]anti-clockwise
C) \[\frac{3v}{4l},\]clockwise
D) \[\frac{4v}{3l},\]clockwise
Correct Answer: C
Solution :
By law of conservation of angular momentum \[\tan \theta =\frac{r}{h/2}\] \[\theta ={{45}^{o}},\] \[r=\frac{h}{2}\] \[\theta ={{45}^{o}}\] \[n'=\frac{v}{v-{{v}_{s}}}\times n\] (anti-clockwise) Not that clockwise or anti-clockwise rotation can only be determined here by the given figure.You need to login to perform this action.
