An object is to be seen through a simple microscope of power \( 8 \mathrm{D} \). Where should the object be placed to
\( \mathrm{P} \)
produce maximum angular magnification? The least
W
distance for distinct vision is \( 25 \mathrm{~cm} \) :
(1) \( 6.54 \mathrm{~cm} \)
(2) \( 5.59 \mathrm{~cm} \)
(3) \( 7.07 \mathrm{~cm} \)
(4) \( 8.33 \mathrm{~cm} \)
