A) \[\frac{\ell }{n+5}\]
B) \[\frac{2\ell }{n+5}\]
C) \[\frac{5\ell }{n+5}\]
D) \[\frac{7\ell }{n+5}\]
Correct Answer: C
Solution :
[c] \[nS=(n+5)v\] \[(S-v)=\frac{5v}{n}\] ??(i) \[n\ell =\left( n+5 \right)v\] ??..(ii) Least count \[=S-v=\frac{5\ell }{n+5}\]You need to login to perform this action.
