Torque on a Box

APPH12-10PNEX

A force of $25\text{ N}$ is applied perpendicular to a box at a distance of $1.5\text{ m}$ above the ground. The box has a height of $3\text{ m}$ and a mass of $15\text{ kg}$. The box does not slide. Instead, it begins to tip over with the axis of rotation marked by an $x$ on the diagram.

What is the initial torque applied to the box?

A

$75\text{ N} \cdot \text{m}$

B

$37.5\text{ N} \cdot \text{m}$

C

$45\text{ N} \cdot \text{m}$

D

$22.5\text{ N} \cdot \text{m}$
