Question A plano-convex lens of refractive index 1.5 and radius of curvature \( 30 \mathrm{~cm} \) is silvered at the curved surface. Now, this lens has been used to form the image of an object. At what distance from this lens, an object be placed in order to have a real image of the size of the object?
(A) 20 cm
(B) 30 cm
(C) 60 cm
(D) 80 cm📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
