A spherical mirror forms an image of magnification 3. The object distance, if focal length of mirror is $24 cm$ , may be

Options:

Answer:

Solution:

$m = \frac{f}{f - u}$ If $m = + 3$ , then $3 = \frac{- 24}{- 24 - u}$ or $- 24 - u = - 8$ or $u + 24 = 8$ or $u = 8 - 24 cm = - 16 cm$ If $m = - 3$ , then $- 3 = \frac{- 24}{- 24 - u}$ $u + 24 = - 8$ or $u = - 32 cm$
