A linear object of size \( 1.5 \mathrm{~cm} \) is placed at \( 10 \mathrm{~cm} \) from a lens of focal length \( 20 \mathrm{~cm} \). The optic centre of lens and the object are displaced a distance \( \Delta \).
\( \mathrm{P} \) The magnification of the image formed is \( m \). (Take optic centre as origin). The coordinates of image of
W \( A \) and \( B \) are \( \left(x_{1}, y_{1}\right) \) and \( \left(x_{2}, y_{2}\right) \) respectively. Then
(a) \( \left(x_{1}, y_{1}\right)=(-20 \mathrm{~cm},-2 \mathrm{~cm}) \)
(b) \( \left(x_{2}, y_{2}\right)=(-20 \mathrm{~cm}, 2 \mathrm{~cm}) \)
(c) \( m=5 \)
(d) \( m=4 \)
