Geometrical Optics question

2025 · 4 Apr · Shift 1 · Q61

JEE MainPhysicsGeometrical OpticsMCQ+4 / −1
When an object is placed 40 cm away from a spherical mirror an image of magnification 12\frac{1}{2}21​ is produced. To obtain an image with magnification of 13\frac{1}{3}31​, the object is to be moved :
  1. A
    20 cm away from the mirror.
  2. B
    20 cm towards the mirror.
  3. C
    80 cm away from the mirror.
  4. D
    40 cm away from the mirror.
