We are given a concave mirror.
Here,
Object size, h = + 5.0 cm
Object distance, u = - 25 cm
Radius of curvature, R = - 30 cm [R is -ve for a concave mirror]
Therefore,
Focal length,
Now, using the mirror formula,
we have,
i.e.,
Magnification,
Image size,
As v is (-)ve, so a real, inverted image of height 7.5 cm is formed at a distance of 37.5 cm in front of the mirror.
