When bodies are in contact with each other then
- a)contact forces are equal and in same direction
- b)contact forces are not equal and in same direction
- c)contact forces are equal and opposite in direction
- d)contact forces are not equal and opposite in direction
Correct answer is option 'C'. Can you explain this answer?

When bodies are in contact with each other thena)contact forces are eq...
Explanation:according to newton's third law of motion for every action there is always equal and opposite reaction or the mutual actions of two bodies upon each other. Whenever two objects interact with each other, then the pair of forces acting on them are equal in magnitude and opposite in direction.Contact forces are mutual forces (action and reaction)

When bodies are in contact with each other, the contact forces between them are equal and opposite in direction. This is known as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Explanation:
Contact Forces:
Contact forces are the forces that arise when two objects physically interact with each other. These forces can include friction, normal force, tension, and compression. When two bodies are in contact, they exert forces on each other due to their interaction.
Newton's Third Law of Motion:
Newton's third law of motion states that if body A exerts a force on body B, then body B exerts an equal and opposite force on body A. Mathematically, this can be expressed as FAB = -FBA, where FAB is the force exerted by body A on body B and FBA is the force exerted by body B on body A.
Equal and Opposite Contact Forces:
When two bodies are in contact, they exert contact forces on each other. According to Newton's third law, these contact forces are equal in magnitude and opposite in direction. This means that if one body exerts a force on the other body, the other body exerts an equal and opposite force on the first body.
Example:
For example, consider a person standing on the ground. The person exerts a downward force on the ground due to their weight. According to Newton's third law, the ground exerts an equal and opposite force on the person, known as the normal force. This normal force prevents the person from sinking into the ground.
Similarly, when you push a book on a table, you exert a force on the book in the forward direction. According to Newton's third law, the book exerts an equal and opposite force on your hand in the backward direction. This is why you feel a resistance when pushing the book.
Conclusion:
In conclusion, when bodies are in contact with each other, the contact forces between them are equal and opposite in direction. This is a result of Newton's third law of motion, which states that every action has an equal and opposite reaction. Understanding this principle is crucial in analyzing the forces acting on objects in contact and predicting their behavior.
