An object is kept on the principal axis of a convex mirror of focal length 10 cm at a distance of 10 cm from the pole. The object starts moving at a velocity 20 mm/s towards the mirror at an angle 30∘ with the principal axis. What will be the velocity of its image and the angle it makes with the principal axis at that instant?
