Question

A boy while playing with two magnets, got familiar with their attractive and repulsive properties. He observed that the magnets are either attracting or repelling each other from a distance. From this, we can conclude that:

• A. Contact is necessary for a force to act.
• B. Non-contact forces do not exist.
• C. Force may be in contact or not in contact depending upon its nature.
• D. No contact is necessary for a force to act.

Answer 1

The correct option is C Force may be in contact or not in contact depending upon its nature.

In the above case, nature of magnetic force is observed. Like poles repel each other and unlike poles attract each other. For force to act two bodies must interact with each other in some way. This can happen when the bodies are in contact or even when they are not in contact.
