The distance between an object and a divergent lens is $m$ times the focal length of the lens. The linear magnification produced by the lens is

Options:

Answer:

Solution:

$u = - mf$ $\frac{1}{v} - \frac{1}{( - m f )} = - \frac{1}{f} \Rightarrow \frac{1}{v} = - \frac{1}{f} (1 + \frac{1}{m}) \Rightarrow - \frac{v}{u} = (\frac{1}{1 + m})$
