A convex mirror of focal length 10 cm, produces a virtual image of ( 6 1 ) t h size of the object. Distance (in cm) of the object from the mirror is :-

For a convex mirror the virtual image is erect, so m is positive: m = f + u f = 6 1 (u = object distance). 6 f = f + u ⇒ u = 5 f = 50 cm . Answer: 50.

A convex mirror of focal length 10 cm, produces a virtual image of $(\frac{1}{6})^{t h}$ size of the object. Distance (in cm) of the object from the mirror is :-

Answer:

Solution:

For a convex mirror the virtual image is erect, so m is positive: $m = \frac{f}{f + u} = \frac{1}{6}$ (u = object distance).

$6 f = f + u \Rightarrow u = 5 f = 50 cm$ . Answer: 50.
