Question

Draw the ray diagram in each case to show the position and nature of the image formed when the object is placed:
At 2f of a convex lens

Answer 1

Prefer the above diagram for your answer...

Answer 2

Image: Real, inverted, same size at 2F

Explanation:

When an object is placed at 2F of a convex lens, the light rays will be converged after refraction through the lens. The light rays will converge at 2F on the other side of the lens. The image so formed will be the same size as the object, and real. But the image will be inverted (upside-down image). The absolute value of the magnification is exactly 1.
