Vedclass · Answer

(C) The angular resolution $	heta$ is given by the ratio of the distance between two dots $x$ to the distance $d$ from the eye, i.e., $	heta = \frac{x}{d}$.Given that the printer prints $300 	ext{ dots per inch}$, the distance between two adjacent dots $x$ is $x = \frac{1 	ext{ inch}}{300} = \frac{2.54 	ext{ cm}}{300}$.Substituting the values into the formula: $5.8 	imes 10^{-4} = \frac{2.54 	ext{ cm} / 300}{d}$.Rearranging for $d$: $d = \frac{2.54}{300 	imes 5.8 	imes 10^{-4}} 	ext{ cm}$.$d = \frac{2.54}{0.174} 	ext{ cm} \approx 14.597 	ext{ cm}$.Thus, the minimal distance is approximately $14.59 	ext{ cm}$.
