Question
Which of the following is NOT a contact force?ElectricAppliedFriction TensionSpring
Solution
The force that is NOT a contact force among the options given is Electric force.
Here's why:
-
Contact forces are those types of forces that result when the two interacting objects are perceived to be physically contacting each other.
-
Examples of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces.
-
Electric force, on the other hand, is a non-contact force. Non-contact forces are those types of forces that result even when the two interacting objects are not in physical contact with each other, yet are able to exert a push or pull despite their physical separation.
-
The electric force (also called the electromagnetic force) is a type of physical interaction that occurs between electrically charged particles. This force is one of the four fundamental forces and it operates over any distance, not requiring physical contact.
So, the answer is Electric force.
