A) 58.59 degree
B) 58.77 degree
C) 58.65 degree
D) 59 degree
Correct Answer: C
Solution :
30 V.S.D. \[\square \to \] 29 M.S.D. 1 V.S.D. \[\to \] \[\frac{29}{30}\]M.S.D. \[=\frac{29}{30}\times 0.5\] least count of vernier = 1 M.S.D. - 1 V.S.D. \[={{0.5}^{o}}-\frac{29}{30}\times {{0.5}^{o}}\] \[=\frac{{{0.5}^{o}}}{30}\] Reading of vernier = M.S. reading + V.S reading \[\times \] least count \[={{58.5}^{o}}+9\times \frac{{{0.5}^{o}}}{30}\] \[=58.65\]You need to login to perform this action.
