Question
Force acting in simple harmonic motion is always:
- Directly proportional to the square of the displacement
- Inversely proportional to the displacement
- Inversely proportional to the square of the displacement
- Directly proportional to the displacement
Hint:
, F = −kx,
The correct answer is: Directly proportional to the displacement
- The force responsible for the motion is always directed toward the equilibrium position and is directly proportional to the distance from it. That is, F = −kx, where F is the force, x is the displacement, and k is a constant. This relation is called Hooke's law.
- So Directly proportional to the displacement
