In Figure. , find the position of final image formed.

Text Solution

Verified by Experts

For convex lens:
`v=(uf)/(u+f)=(-15xx10)/(-15+10)=30cm`
For concave lense: `u=(30-25)=5cm`
`u=(30-25)=5cm`
`v=(uf)/(u+f)=(5(-10))/(5-10)=10cm`
So, final image is formed 10 cm to the right of the concave lens.
