Question

In the game of cricket, the stumps fall down when the ball strikes them. This is an example of
A. Contact force.
B. Non-contact force.
C. Displacement force.
D. None.

Answer 1

In this question, the concept of the types of forces used is the contact force, non-contact force, displacement force. The concept of the contact force is when two objects physically collide or interact with each other there is contact force involved.

Complete step by step solution:
When two objects physically collide or interact with each other there is contact force involved.

There are many types of contact forces such as-tension force, spring force, normal reaction, friction, air resistance, weight, applied contact forces.

Non-contact forces are these forces that mainly act between two bodies that do not require any physical contact.

There are many types of non-contact forces such as-Gravitational force, electrical force, magnetic forces.

Now, in the game of cricket when the ball strikes the stumps they fall down. This is an example of contact force.

In contact force two bodies are required to collide or interact with each other. Here the ball and the stumps are two bodies as they collide with each other and stumps fall down due to the contact forces. Here force is exerted by the ball and the force is exerted on the stumps.

Hence in the game of cricket when the ball strikes the stumps they fall down, this is an example of contact force.

Thus, Option-(A) is the correct answer.

Note: We can see sometimes non-contact forces are acting between two bodies that are actually in contact with each other such as-sitting in front of a television. There two forces are acting- gravity which is non-contact force and then the weight and compression which are contact forces.
