Question

A real image is formed by a convex lens. When it is cemented with a concave lens, again the real image is formed. The real image formed by concave lens :

A
shifts towards the lens system
B
shifts away from the lens system
C
remain in its original position
D
shifts to infinity
Solution
Verified by Toppr

Concave lens has property of diverging the incident rays.
So, when a concave lens is introduced after a convex lens, real image position will shifts away from the lens combination system.
