Answer

a. $f = 10 \, \text{cm}$ <br /><br />b.i. $\frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i} \implies \frac{1}{10} = \frac{1}{5} + \frac{1}{d_i} \implies d_i = 10 \, \text{cm}$ <br /><br />b.ii. $M = -\frac{d_i}{d_o} \implies M = -\frac{10}{5} \implies M = -2$ <br /><br />c. The image is inverted and real.
