Answer:
(d) None of these , x = 2
Explanation :-
- Let us understand what we mean by image with respect to x or y axis . This sentence implies that the mirror is x axis or y-axis and we have to find image.
- Here,we have to find image with respect to x = 0 which is y-axis . x = -2 is a line parallel to y -axis at a distance 2 unit left from it.
- Therefore,image would be formed at the same distance in the right side of the mirror ,and thus a line parallel to y-axis two unit right from y-axis is x = 2 .
Additional information
- Had the mirror been y = 0,the answer would have been x = -2.
