Answer 2

Explanation:

1.Principal focus is defined as the point in front of a concave mirror at which it focusses the reflected rays rays(in this case incident beam of light is paraxial ie make very small angle with normal).

2.For paraxial rays,f=R/2 where R is Radius of curvature hence f=10cm.

3.So,only a concave mirror can form a virtual,erect and enlarged image(in terms of spherical mirrors).

4.Convex mirrors always form virtual,erect and diminished images which makes them ideal as rear view mirrors.
