Q
Q: A 4 kg object is at rest on a table. What is the force of static friction if no external force is applied?
Solution:
If no external force is applied, the force of static friction is 0 N.
Steps: 3
Show Steps
Step 1: Understand that static friction is the force that keeps an object at rest when no external force is applied.
Step 2: Recognize that if no external force is acting on the object, it will not move.
Step 3: Since the object is at rest and no force is trying to move it, the force of static friction must also be 0 N.
