If a body is pulled on an inclined plane at an angle greater than the angle of friction, the body will start to move up the inclined plane. Let's consider two scenarios based on whether the applied force is greater or equal to the limiting friction.
Applied Force Greater than Limiting Friction: If the applied force is greater than the limiting friction, the body will experience a net force in the upward direction along the inclined plane. As a result, the body will start to move up the incline. The magnitude of the net force will be the difference between the applied force and the limiting friction force, which opposes the motion. The body will accelerate up the inclined plane.
Applied Force Equal to Limiting Friction: If the applied force is exactly equal to the limiting friction, the body will be in a state of equilibrium, and it will not move up or down the inclined plane. The opposing forces are balanced, resulting in no net force along the incline. The body will remain at rest or continue moving with a constant velocity if it was already in motion.
It's important to note that the angle of friction refers to the maximum angle at which an object can be inclined before it starts to slide due to the force of friction. If the applied force is less than the limiting friction, the body will not move and will remain in equilibrium.
