A rod of length `5cm` lies along the principle axis of a concave mirrror of focal length `10cm` in such in way that the end farther from the pole is `15cm` away form it, Find the length of the image.

Text Solution

Verified by Experts

The correct Answer is:

Infinitely large.

imag eof end `f` and `C` is formed at infinity and `C` respectively. Hence image is of infinite length.
