Problem

A concave lens of focal length

20\,\text{cm}

is placed

10\,\text{cm}

to the left of a convex lens of focal length

15\,\text{cm}

on the same principal axis. An object is located

to the left of the concave lens. The position of the final image relative to the convex lens is a)

12\,\text{cm}

to the right of the convex lens b)

47\,\text{cm}

to the left of the convex lens c)

47\,\text{cm}

to the right of the convex lens d)

22\,\text{cm}

to the left of the convex lens
