Answer 2

${\huge{\underline{\black{\bf{Answer:}}}$

When an object is near a plane mirror, the image is erect, virtual and of the same size at the object. A concave mirror gives a magnified and erect image of a nearby object whereas a convex mirror gives an erect and diminished image. For the rear view mirror in a car.
