Two equal-magnitude forces are applied to a door at the doorknob. The first force is applied perpendicular to the door, and the second force is applied at \( 30^\circ \) to the plane of the door. Which force exerts the greater torque about the door hinge?

- **A.** the first force (applied perpendicular to the door).
- **B.** the second force (applied at an angle).
- **C.** Both forces exert zero torque.
- **D.** Both forces exert equal non-zero torques.
