An object O is placed in front of a small plane mirror M $_{1}$ and a large convex mirror M $_{2}$ of focal length $f$ . The distance between O and M $_{1}$ is $x$ , and the distance between M $_{1}$ and M $_{2}$ is $y$ . The images of O formed by M $_{1}$ and M $_{2}$ coincide. The magnitude of $f$ is

Options:

Answer:

Solution:

As this is a convex mirror, $f$ is positive, hence magnitude of $f = \frac{x ^{2} - y ^{2}}{2 y}$ .
