Ron placed an object at a distance of 2 m from a plane mirror. He then shifted the object 0.5 m away from the mirror. What is the total distance between the object and its image?

Answer: C. 5 m

After shifting, the object is 2 + 0.5 = 2.5 m from the mirror. In a plane mirror the image is as far behind the mirror as the object is in front, i.e. 2.5 m. Total distance = 2.5 + 2.5 = 5 m.
