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


please give me a correct answer

Answer 1

here is your answer

m=2

ho=10

m=hi/ho

2=hi/10 (cross multiply)

hi=10*2

hi=20.

Answer 2

Answer:

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

u

−v

For real image, m = -2

So,

10 cm

−v

v = 20 cm

The image is formed at a distance of 20 cm.

Hence, this is the required solution.
