Answer
(a) nearsightedness
(b) $74.1cm$
Work Step by Step
(a) We know that the negative sign of the power of the lens shows that the lens is a diverging lens. The diverging lens is used to clear off the nearsightedness. The person suffering from the nearsightedness cannot see at the infinite distance or beyond the far point. Thus, the person has nearsightedness.
(b) We know that
$f_{m}=\frac{1}{P(diopters)}$
$f_{m}=\frac{1}{-1.35diopters}$
$\implies f_{m}=-74.1cm$
Now $q=\frac{1}{\frac{1}{f}-\frac{1}{p}}$
We plug in the known values to obtain:
$q=\frac{1}{\frac{1}{-74.1cm}-\frac{1}{\infty}}$
$\implies q=74.1cm$
