Answer 2

To make an image real, inverted and larger than the object with a convex lens, the object should be placed (c) Between F and 2F of lens.

Explanation:

• Convex lens is type of spherical lens which possess at least one surface that is curved outwards. It is thinner at its edges than at its centre.
• Convex lens are also called converging lens as it converges the rays that are parallel to principal axis on a point called focus.
• Focus is a point on principal axis where rays parallel to principal axis and coming from infinity converge or diverge.
• Centre of curvature is 2F.
• It can form real images which are inverted and smaller or larger or of same size as the object.
• It can form virtual images which are erect and magnified i.e. larger than object.

To form real, inverted  and magnified image, the object should be between focus (F) and centre of curvature (2F).
