The diagram shows an eyepiece graticule and part of a stage micrometer scale viewed at $\times 100$ magnification. How is the value, in $\mu\text{m}$, for one eyepiece graticule unit determined?

  • Adivide $100$ by $0.1$ and multiply by $1000$
  • Bdivide $100$ by $0.1$ and multiply by $1000$ divided by $100$
  • Cmultiply $0.1$ by $1000$ and divide by $100$
  • Dmultiply $0.1$ by $1000$ and divide by $100$ then divide again by $100$
