Problem

For a concave spherical mirror of focal length ff, an object is to be positioned so that the resulting image is inverted and three times as tall as the object. Which of the following object distances sos_o satisfies this requirement? (a) so=3f4s_o = \dfrac{3f}{4} (b) so=4f3s_o = \dfrac{4f}{3} (c) so=2f3s_o = \dfrac{2f}{3} (d) so=3f2s_o = \dfrac{3f}{2}
