Question

In the free-body diagram, the magnitude of the normal force is 35 N, the friction force is 15 N, and the net force is 70 N. What is the magnitude of the applied force? 

The image depicts a free body diagram showing a box with vectors representing different forces acting on it. The diagram serves to illustrate the concept of forces in equilibrium and the interaction of forces on a body.

- **Fₙ (Normal Force):** An upward arrow indicates the normal force acting perpendicular to the surface, supporting the box against gravity.

- **Fₐ (Applied Force):** An arrow pointing to the right represents the applied force that is trying to move the box horizontally across the surface.

- **Fₒ (Frictional Force):** An arrow pointing to the left denotes the frictional force, which opposes the motion of the box as it interacts with the surface.

- **F₉ (Gravitational Force):** A downward arrow illustrates the gravitational force acting on the box, pulling it towards the Earth.

This diagram is typically used in physics education to explain equilibrium, where the sum of forces in each direction is zero, resulting in the box being stationary or moving with constant velocity.
