Solution

## The correct option is D 4 m/s towards leftO= Object i=image As the object is approaching mirror with 2 ms−1, then the image will also approach the mirror with same speed. v0 , speed of object =−2 ms−1(right)vi , speed of image =−2 ms−1(right) speed of image with respect to object =Vi−V0=2−(−2)=4 ms−1(right)
