A circular disk of radius $R=2.0\text{ m}$ is subject to three different coplanar forces at different locations, as shown above.

What is the magnitude and direction of the net torque on the disk?

A

$1.0 \text{ N}\cdot \text{m}$, into the page.

B

$4.0 \text{ N}\cdot \text{m}$, into the page.

C

$6.4\text{ N}\cdot \text{m}$, out of the page.

D

$9.2 \text{ N}\cdot \text{m}$, out of the page.

E

$24 \text{ N}\cdot \text{m}$, into the page.
