Two plane mirrors are parallel to each other and spaced \( 20 \mathrm{~cm} \) apart. An object is kept in between
\( \mathrm{P} \)
them at \( 15 \mathrm{~cm} \) from \( \mathrm{A} \). Out of the following at
W
which point(s) image(s) is/are not formed in mirror \( \mathrm{A} \) (distance measured from mirror \( \mathrm{A}) \) :
(1) \( 15 \mathrm{~cm} \)
(2) \( 25 \mathrm{~cm} \)
(3) \( 45 \mathrm{~cm} \)
(4) \( 55 \mathrm{~cm} \)
