Question
Which frictional force is acting here?
- Static friction
- Sliding friction
- Rolling friction
- Fluid friction
Hint:
The frictional force acting when an object shows no motion even on the application of an external force is static friction.
The correct answer is: Static friction
The frictional force acting here is static friction.
- Static friction holds an object from moving.
- The object in the given diagram shows no movement on the application of an external force.
- An object subjected to static friction doesn't move unless the static friction is removed.
