When an object approaches a convex lens from infinity, the image formed by it shifts

A converging lens can from a virtual image if the object is placed

If an object is placed at the focus of a convex lens, where is the image formed?

An object is placed at the focus of a concave lens. Where will be image ?

A point object O approaches a biconvex lens of focal length 40 cm along its optic axis with a speed of 10 m/s while the later receeds away from the former with a speed of 4 cm/s. Find the speed and direction of motion of the image when the object is at a distance of 60 cm from the lens.

An object is approaching a thin convex lens of focal length 0.3 m with a speed of 0.01 m s^(-1) .Find the magnitudes of the rates of change of position and lateral magnification of image,when the object is at distacne of 0.4 m from the lens.
