Please specify if mirror and object each have individual speed "V" or V is there relative velocity? In the solution it is mentioned as "Relative Velocity" which is not clear in the question

Ans 4:

Soham Singh from JMPS, Jammu
Class : Class 7
Even though both the object and the mirror are moving away, it talks about the speed of the image with respect to the mirror. The speed wouldn't be double in this case and hence the correct option should be B) and not A)
