A plane mirror `(M_1)` and a concave mirror `(M_2)` of focal length 10 cm are arranged as shown in figure. An object is kept at origin. Answers the following questions. (consider image formed by single reflection in all cases).

if concove mirror is replaced by another plane mirror parallel to x-axis, then coordinates of image formed by `(M_2)` are

Options

A. `(40 cm, 20 cm)`
B. `(20 cm, 40 cm)`
C. `(-20 cm, 20 cm)`
D. None of these

Answer

D

Explanation

Plane mirror forms at equal distance on opposite sides
Hence, `x=0, y=40 cm`.
