Question

4. Which of the following is non
contact force?​

Answer 1

Answer:

An apple falling down from a tree is one of the best examples of non contact force.

Iron pins attracted in the presence of a magnet bar without any physical contact.

Falling of raindrops on earth is also an example of non-contact force.

The charging of the hair and attraction of paper bits towards it.

Explanation: A non-contact force is a force applied to an object by another body that is not in direct contact with it. Non-contact forces come into play when objects do not have physical contact between them or when a force is applied without any interaction. When compared to the types of contact forces, there are very few non-contact forces.
