Question

Which one of the following is not an example of non-contact force?​

Answer 1

Explanation:

The only left force is muscular force. This means that muscular force is not a non-contact force. Hence, option D is correct. Note- Spring force is also an example of contact force.

Answer 2

Answer:

• Muscular force can be applied only while in contact with the object. So, it is a contact force, not a non-contact force.
