Plzz answer question no 11

Plzz answer question no 11 vuncave mirror of focal length f produces an image n times the size of the object. Ifthe image is real then the distance of the object from the mirror, is (b) {(n— l)/n} f (c) {(n+ l)/n} f 11. A convex mirror of focal length f produces an image ( l/n)th of the size of the object. The distance ofthe object from the mirror is (a) nf (c) (n + l)/f (b) f/n Image Location, Magnification 12. What is the magnification when the object is placed at a distance of2fform the pole ofa convex mirror?
