59. For a convex mirror with radius of curvature R = 10 cm, if an object is placed 15 cm in front the mirror, what is the magnification of the image and is it a real or virtual? Upright or inverted? (mirror’s equation: 1/p+1/q = 2/R)
(A) 3.75 cm (virtual behind mirror) and M = 0.25, inverted
(B) 7.50 cm (virtual behind mirror) and M = 0.5, upright
(C) 3.75 cm (real in front mirror) and M = 0.5, inverted
(D) 7.50 cm (real in front mirror) and M = 0.25, inverted
(E) 3.75 cm (virtual behind mirror) and M = 0.25, upright
