The static frictional force is
The static frictional force is
- A. self adjustable.
- B. not self adjustable.
- C. scalar quantity.
- D. equal to the limiting force.
Step-by-step solution
Static friction is a force that opposes the initiation of relative motion between surfaces. It adjusts its magnitude from zero up to a maximum value (limiting friction) to match the applied force, hence it is self-adjusting. Option B is false; option C is true but not specific; option D is only true when the applied force reaches the limiting value.
