Question

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

Answer 1

For lens,
`(1)/(v) - (1)/(u) = (1)/(f)`
`(1)/(v) - (1)/(-15) = (1)/(-10) rArr v = +- 30cm`
Hence it is object for mirror
`u = -15cm`
`(1)/(v) + (1)/(-15) = (1)/(-10) rArr v = +30`
Hence final image will from at a distance `30cm` formt the lens towards left.
