Question
Which one of the following forces doesn't act on the spring and block system?
- Elastic force
- Frictional force
- Gravitational force
- Tension force
Hint:
Frictional force doesn't act on spring and block system
The correct answer is: Tension force
Tension force acts on the spring being pulled down by the object. Gravitational force acts on the object. And elastic force is also present.
