Question

A concave mirror produce two times magnified real image of an object placed at 10cm in front of it. find the position of the image

Answer 1

u -10
m -2
-v/u equal to -2
v/u 2
v 2u 2 (-10) -20

Answer 2

Answer : The image is formed at a distance of 20 cm.

Explanation :

Given that a concave mirror produce two times magnified real image of an object.

Object distance, u = 10 cm

The magnification of a concave mirror is given by :

$m=\dfrac{-v}{u}$

For real image, m = -2

So,

$-2=\dfrac{-v}{10\ cm}$

v = 20 cm

The image is formed at a distance of 20 cm.

Hence, this is the required solution.
