Answer:
Refer to the attached image.
Step-by-step explanation:
To understand the forces acting on a box at rest on an inclined surface, it's essential to correctly illustrate and identify all the forces, including their components, considering the inclined plane as the reference.
When a box is at rest on an inclined surface, the following forces act on it:
- Gravitational Force (Weight): This force acts vertically downward and is represented as W or mg, where m is the mass of the box and g is the acceleration due to gravity.
- Normal Force: This force acts perpendicular to the surface of the incline and is represented as N. It balances the perpendicular component of the gravitational force.
- Frictional Force: This force acts parallel to the surface of the incline and opposes the motion of the box. Since the box is at rest, the frictional force (f) is static friction, preventing the box from sliding down.
