Question

Is it true that the reaction of a gravitational force is always gravitational, of an electromagnetic forcer is always electromagnetic and so on? If no, then give some examples.

Answer 1

Answer:

No. It is not so.

Explanation:

Suppose we keep a book on a table. It is attracted to the center of the earth due to gravitational force. The book is stationary due to the reaction force of the table, which can be termed as normal reaction force.

So the reaction to the gravitational force ( a non contact force) is a normal reaction force ( A contact force).
