An object moving towards mirror as shown in the figure.

A. the speed of image will be 2 m/s irrespective the speed of mirror.
B. the speed of image will be 2 m/s only when speed of mirror is zero.
C. the speed of image will be 6 m/s when mirror is moving towards object with 2 m/s.
D. the speed of image will be 6 m/s, where mirror is moving away from object with 2 m/s.
E. the speed of image will be 2 m/s, where mirror is moving away from object with 2 m/s.

Choose the correct answer from the options given below:

B, C only

The correct answer is Option (2) → B, C only

(B) When the speed of the mirror is zero, the speed of the image will be 2 m/s because it is a plane mirror and the object and image distance is same from the mirror.

(C) When the mirror is moving towards the object with 2 m/s the total speed of the image will be the combined effect of object's speed and the mirror's speed.
