(A) Given R = 30 cm
Magnification (m) =
For convex mirror, virtual image is formed for real object, therefore, is +ve
The mirror formula,
Magnification,
If the distance between object and its two times magnified virtual image produced by a curved mirror is 15 cm, the focal length of the mirror must be [2024]
