The figure below shows an angler with a fishing pole that makes an angle of 20.0° above the horizontal. The distance from the angler's hand to the tip of the pole is L = 2.09 m. A fish is on the line, and it pulls the line with a force of F = 105 N at an angle 37.0° below the horizontal. What is the magnitude of the torque (in N · m) exerted by the fish about an axis perpendicular to the page and passing through the angler's hand?

Question

The figure below shows an angler with a fishing pole that makes an angle of 20.0° above the horizontal. The distance from the angler's hand to the tip of the pole is L = 2.09 m. A fish is on the line, and it pulls the line with a force of F = 105 N at an angle 37.0° below the horizontal. What is the magnitude of the torque (in N · m) exerted by the fish about an axis perpendicular to the page and passing through the angler's hand?

The image illustrates a person fishing from a boat, depicting the angles and forces involved in the process. The fishing rod is shown as a lever with length labeled \( L \). The rod makes a \( 20.0^\circ \) angle with the horizontal plane of the boat. The fishing line extends from the tip of the rod at a \( 37.0^\circ \) angle downward towards the water, indicating the tension and direction of force exerted by the fish.

The force vector \( \vec{F} \) is represented as a blue arrow along the line of the fishing line, suggesting the direction and possibly the magnitude of the force applied by the fish. The fish is shown pulling on the line underwater, demonstrating the interaction between the fisher and the fish.

This diagram can be used to explain principles of forces, angles, and equilibrium in physics, particularly in the context of simple machines and vectors in mechanics.
