A line is drawn normal to the curve $y = \frac { 2 } { x ^ { 2 } }$ at the point on the curve where $x = 1$.
This line cuts the $x$-axis at $P$ and the $y$-axis at $Q$.
The length of $P Q$ is
A $\frac { 3 \sqrt { 5 } } { 2 }$
B $\frac { 3 \sqrt { 17 } } { 4 }$
C $\frac { 7 \sqrt { 17 } } { 4 }$
D $\frac { 35 } { 4 }$
E $\frac { 35 \sqrt { 5 } } { 2 }$
F $\frac { 3 \sqrt { 17 } } { 2 }$
