Answer 2

If a convex lens is used to read a newspaper, then the object is placed at a normal distance from the eye.

• A convex lens is often used as a magnifying glass, because it conceals opposing light beams into one concentrated light beam.  It helps in magnifying a put object.
• When positioned between the radius of curvature and focal length, a convex lens gives a magnified image of an object.
• Magnification is even more fitting for convex lenses which have shorter focal length. Therefore, a convex lens should be used for reading small letters, where the newspaper is at a normal distance from the eye.
