physics.cie said:I agree with your answer. But is that friction enough to avoid attraction on inclined plane
An inclined plane is a simple machine that consists of a flat surface that is set at an angle to the ground. It is used to help lift or move objects by reducing the amount of force needed to do so.
An inclined plane works by increasing the distance over which a force is applied, which reduces the amount of force needed to move an object. This is known as the mechanical advantage of the inclined plane.
The mechanical advantage of an inclined plane can be calculated by dividing the length of the inclined plane by its height. This equation is MA = length/height.
Friction can reduce the mechanical advantage of an inclined plane, as it opposes the motion of the object being moved. Therefore, the steeper the angle of the inclined plane, the less friction will affect the object.
Inclined planes can be found in many everyday objects, such as ramps for wheelchairs and cars, escalators, and slides. They are also used in construction for moving heavy objects and in agriculture for loading hay onto trucks.
