Answer:

As we know that,

The focal length associated with the mirror as displayed in the mirror would be determined through the difference that lies between the focus(where the image formed) and the

Focal length = concave mirror's distance(P) - position of screen

ff = 15.6 - 4.6=15.6−4.6

∵ f = 11 cmf=11cm

Thus, option B i.e. 11cm being the focal length of the concave mirror is the correct answer.
