Question

Give two examples of each central and non central force.

Answer 1

- Hint –In order to deal with this question first we will define both the force central as well as non central forces, then according to its definition and on the basis of its application we will give examples of both the central as well as non central force.

Complete step-by-step solution -

Central force:
A central force on an object is a force that is directed along the line joining the object and the origin.
Examples of central force are:
A central force on an object is a force pointing down the line connecting the object and its origin
Two familiar examples of central force are gravitational force and Coulomb force
Uniform motion
Force due to Gravitation.
Projectile motion.
Uniform accelerated motion

Non central force:
A force between two particles not guided down the line that separates them; a tensor force between two nucleons, for example.
Examples of non central force are:
Nuclear force based on particle spin
Tensor force between two nucleons
Magnetic system acting between two current carrying loops.

Additional information- A force is just a simple push or pull applied on any object which results from the interaction of the object with another object. If the two objects touch, there is an impact on each of the objects.
As a force acts (pushes or pulls) on an object, it shifts the momentum or trajectory of the object (that is, it makes it accelerate). The greater the force, the more the body accelerates. There is an equivalent force (called a reaction) acting in the opposite way, as a force acts on an object.

Note- Central force is the force which points radially, and the magnitude depends on the distance from the source. The magnitude of the central force only depends on the distance between the object and the centre. In order to solve these kinds of problems, students must remember to define different types of force.
