- C. Spring constant.
- D. Energy stored in the spring.
Answer
Extension of the spring.
Explanation
'e' in the equation F = ke represents the extension of the spring, which is the increase in length when a force is applied.
Common mistake
Misunderstanding Hooke's Law
Students often confuse the relationship in Hooke's Law, thinking that force and extension are not directly proportional beyond the limit of proportionality.
To fix this, students should practice identifying the limit of proportionality on force-extension graphs and understand that Hooke's Law applies only within this limit.
