A point object \( O \) is placed at a distance of \( 20 \mathrm{~cm} \) in front of a
\( \mathrm{P} \) equiconvex lens \( \left({ }^{a} \mu_{g}=1.5\right) \) of focal length \( 10 \mathrm{~cm} \). The lens is placed on a liquid of refractive index 2 as shown in the figure. Image will be formed at a distance \( h \) from lens. The value of \( h \) is
(a) \( 5 \mathrm{~cm} \)
(b) \( 10 \mathrm{~cm} \)
(c) \( 20 \mathrm{~cm} \)
(d) \( 40 \mathrm{~cm} \)
