Pls solve Q19. Also explain..
Dear Student
Given that a concave mirror produce two times magnified erect image of an object.
Object distance, u = -10 cm
The magnification of a concave mirror is given by :
For real image, m = -V/u = 2 ( as image is erect)
=> -V/-10 = 2
=> V /10= 2
=> V = 20
So,
v = 20 cm
The image is formed at a distance of 20 cm behind the mirror.
