Answer:
2
Step-by-step explanation:
To double the force of a spring while keeping other factors constant, you must multiply the spring constant (k) by 2. This relationship is described by Hooke's Law, which states that the force exerted by a spring is directly proportional to its spring constant and the displacement from its equilibrium position. Mathematically, it's represented as:
F = -k * x
Where:
- F is the force applied to the spring.
- k is the spring constant.
- x is the displacement from the equilibrium position.
If you want to double the force (F), you would need to double the spring constant (k) while maintaining the same displacement (x).
