Two plane mirrors are inclined at an angle of 60^(@) . An object is placed between the mirrors. The number of images formed by the two mirrors is

An object is approaching a convex mirror. The ratio of the velocity of the object and that of the object image which is m times magnified is

An object is moving towards a mirror with a velocity of 10 ms^(-1) as shown in the figure. If the collision between the mirror and the object is perfectly elastic, then the velocity of the image after collision with mirror in vector form is
