In the shown figure, multiple images of an object O are formed due to two perpendicular mirrors. If velocity of object is $3 \hat{i} + 4 \hat{j}$ , then velocity of its image $I_{3}$ will be

Options:

Answer:

Solution:

Along the normal to a plane mirror, velocity of image $= -$ velocity of object.

Along the parallel to the plane of the mirror, velocity of image = velocity of object. $I_{3}$ is formed by reflection in both mirrors, so both components reverse: $- 3 \hat{i} - 4 \hat{j}$ .
