Question

For fixed value of main scale division (MSD) the relation between least count (LC) and number of vernier scale division (VSD) will be shown by following graph –

• A. (a)
• A. (b)
• A. (c)
• A. (d)

Answer 1

(c)

Sol. Least count = $\frac { 1 \mathrm { MSD } } { \mathrm { n } }$ so LC µ $\frac { 1 } { \mathrm { n } }$
