The vernier scale used for measurement has a positive zero error of $0.2 \mathrm{mm}.$ If while taking a measurement it was noted that $0$ on the vernier scale lies between $8.5 \mathrm{cm}$ and $8.6 \mathrm{cm}$. Vernier coincidence is $6,$ then the correct value of measurement is $\mathrm{cm}.$

(least count$=0.01 \mathrm{cm}$)

• A

  $8.36 \mathrm{cm}$
• Correct answer
  B

  $8.54 \mathrm{cm}$
• C

  $8.58 \mathrm{cm}$
• D

  $8.56 \mathrm{cm}$

Hence, the correct answer is option: 'B'.
