Q1
If the angle of inclination of a plane increases, what happens to the static friction force acting on an object resting on the plane?
Increases
Decreases
Remains constant
Becomes zero
As the angle increases, the component of gravitational force parallel to the plane increases, which can lead to a decrease in static friction until it reaches its maximum value.

Q
Q: If the angle of inclination of a plane increases, what happens to the static friction force acting on an object resting on the plane?
Solution: As the angle increases, the component of gravitational force parallel to the plane increases, which can lead to a decrease in static friction until it reaches its maximum value.
Steps: 6
Step 1: Understand that static friction is the force that keeps an object at rest on a surface.
Step 2: Know that when a plane is inclined, gravity pulls the object down the slope.
Step 3: Realize that as the angle of the plane increases, the force pulling the object down the slope (parallel to the plane) also increases.
Step 4: Recognize that static friction must counteract this force to keep the object from sliding.
Step 5: Understand that static friction has a maximum value, which depends on the normal force and the coefficient of static friction.
Step 6: Conclude that as the angle increases, the static friction force can decrease until it reaches its maximum value, which is determined by the surface properties.
