Answer 2

Explanation:

Given The human eye has an approximate angular resolution of 5 x 10-4 rad and a typical photo printer prints a minimum 500 dots per inch (1 inch = 2.54  cm) At what minimum distance should a printed page be held so that one does not see individual dots?  

• So we have number of dots in 1 inch will be 500 dots
• So 1 inch = 2.54 cm
• So 2.54 cm has 500 dots.
• So distance between 2 dots will be 2.54 / 500
•                                                   = 0.00508 cm
• So if l represent distance between 2 dots and there is a human eye.
• So we need to find minimum distance so that eye does not see the dots. So the angle formed is theta.
• So we have theta = arc length l / r
•                        So r = l / theta or phi
•                               = 0.00508 / 0.0005
•                       So r = 10.16 cm
• So the minimum distance to hold the sheet will be 10.16 cm
