The action and reaction are equal in magnitude'. Is this statement true ?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement in question is "The action and reaction are equal in magnitude." This relates to Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.

2. **Defining Action and Reaction**: According to Newton's Third Law, when one body exerts a force (action) on another body, the second body exerts a force (reaction) back on the first body that is equal in magnitude but opposite in direction.

3. **Example to Illustrate**: Consider a block of mass (e.g., 5 kg) resting on a table. The block exerts a downward force on the table due to its weight (this is the action). Simultaneously, the table exerts an upward force on the block (this is the reaction).
