Solution

## The correct option is B 10 msec, towards the mirror Object distance from the plane mirror is equal to the image distance from the mirror. Speed (Velocity) is the change in distance over time. Speed, S = Distancetime So, speed of the image is same as that of the object, and the direction is towards the mirror.
