The normal force exerted by the surface of the wedge is normal to the ...
As we know the normal forces act perpendicular to the surfaces of the body kept over the wedges. Thus the normal force exerted by the surface of the wedge is normal to the surface of the base of the body kept over the wedge. The wedges are very useful in the industries, and it has a wide application.

Understanding the Normal Force on a Wedge
The normal force is a critical concept in mechanics, particularly when dealing with inclined surfaces such as wedges. In this scenario, the normal force is essential for understanding how objects interact with these inclined planes.
Definition of Normal Force
- The normal force is the force exerted by a surface that supports the weight of an object resting on it.
- It acts perpendicular (normal) to the contact surface between two objects.
Normal Force on the Wedge
- When an object rests on a wedge, the normal force exerted by the wedge is directed perpendicular to the inclined surface of the wedge.
- This force counteracts the component of the gravitational force acting perpendicular to the surface of the wedge.
Why Option B is Correct
- The normal force acts perpendicular to the base of the body residing over the wedge (option B).
- This is because the body (often a block or another object) makes contact with the surface of the wedge, and the normal force arises from this contact.
Comparison with Other Options
- Option A (Base of the wedge): The normal force pertains to the object resting on the wedge, not the wedge itself.
- Option C (Base of the body just neighbor to the wedge): This might imply a different contact surface, which isn't relevant to the normal force acting on the wedge.
- Option D (Earth's surface): The normal force acts at the interface of the wedge and the resting object, not at the Earth's surface.
In conclusion, understanding the direction and application of the normal force is vital in analyzing forces in mechanical systems, especially in scenarios involving wedges.
