Answer :
i) For a point object the image will also be a point size of same size and at the same distance from the mirror.
(ii) For an eluded object the image is also travel with the same speed in same time travel equal distance but behind the mirror.
Position 1 and 2 represents two different positions of objects (in front of mirror) and their respective images (behind the mirror) at two instances.
Now in the given case, P can not see his image as his image will be formed at the same distance from his present position. Therefore, P will not be able to see his own image. While others can see their images along with P.
