The vernier scale used for measurement has a positive zero error of $\displaystyle 0.2$ mm . If while taking a measurement it was noted that ' $\displaystyle 0$ ' on the vernier scale lies between $\displaystyle 8.5$ cm and $\displaystyle 8.6$ cm, vernier coincidence is $\displaystyle 6$ , then the correct value of measurement is \_\_\_\_ cm . (least count $\displaystyle =0.01 \mathrm{~cm}$ )
Official answer
(3)
8.$\displaystyle 54$ cm
