###### Question details

For a spherical mirror of radius r cm, $\frac{1}{v}+\frac{1}{u}=\frac{2}{r}$$\frac{1}{v}+\frac{1}{u}=\frac{2}{r}$, where u cm is the distance from the mirror to the object and v cm is the distance from the mirror to the image. The magnification is given by $m=\frac{v-r}{r-u}$

Find m in terms of v and u only.

Please provide a step by step awnser with detailed explanation. Thankyou.
