An object is placed 4 cm away from a concave lens of focal length 3 cm. A convex lens of focal length 5 cm is placed 4 cm away from the concave lens in the same direction (so the distance between convex lens and the object is 8 cm). Use any method to figure out if the final image is real/virtual, upright/inverted and find its distance from the convex lens.

Explain in thorough detail.

draw a proper ray diagram for this question.
