Question

a concave mirror produce three times magnified real image of an object placed at 10cm in front of it . where is the image located

Answer 1

may be the image formed in front of the mirror

Answer 2

$\large\sf\underline\red{GIVEN:-}$

$\small\sf{m= -3}$

$\small\sf{u = -10cm}$

$\small\sf{v= ?}$

⠀⠀⠀

Putting these values in the magnification for a mirror:

$\longrightarrow$$\small\sf{m =- \frac{v}{u}}$

$\longrightarrow$$\small\sf{-3 =- \frac{v}{-10}}$

$\longrightarrow$$\small\sf{-3×10 = -v}$

$\longrightarrow$$\small{\boxed{\sf{v= -30cm}}}$

Thus, the image is located at a distance of 30cm in front of the mirror.
