A) \[\frac{V}{l}\]
B) \[\frac{2\pi nV}{l}\]
C) \[\frac{\pi n}{2V}\]
D) None of these
Correct Answer: B
Solution :
As, \[V=at\] and \[\omega =at\] \[2\pi n=\frac{1}{2}a{{t}^{2}}\] and \[l=\frac{1}{2}a{{t}^{2}}\] (as in one turn there is \[2\pi \] radium) \[\Rightarrow \] \[\frac{2\pi n}{1}=\frac{a}{a}=\frac{w}{V}\] \[w=\frac{2\pi n}{l}V\] As two blocks are held together.You need to login to perform this action.
