A) Shifts towards the lens system
B) Shifts away from the lens system
C) Remains at the original position
D) No image is formed
Correct Answer: B
Solution :
\[\frac{1}{F}=\frac{1}{{{f}_{1}}}-\frac{1}{{{f}_{2}}}\] The combination is a convex lens therefore F must be positive. This is possible when \[{{f}_{2}}>{{f}_{1}}.\]This give F greater than\[{{f}_{1}}.\]So, the image will shift away from the lens system. Hence, the correction option is [b].
