Question
120 N of force is being applied, and the static friction is acting on the object. What will be the value of this static friction?
- Less than 120 N
- More than 120 N
- Equal to 120 N
- 0N
Hint:
Static friction is a self-adjusting frictional force.
The correct answer is: Equal to 120 N
When 120 N external force is applied to an object, the static frictional force is created to resist the external force which is equal to 120 N.
- Static friction refers to a self-adjusting frictional force.
- It adjusts its strength against the increase in the applied external force.
- If an external force is applied to an object, the static friction adjusts itself to resist that force and creates a force equal to the applied force which is equal in the magnitude.
- Thus, when 120 N external force is applied to an object, the static frictional force is created to resist the external force which is equal to 120 N.
