Options:

Correct Answer: 0 degrees

Solution:

At resonance, the phase difference between the driving force and the displacement is 0 degrees.

What is the phase difference between the driving force and the displacement in a forced oscillation at resonance?

What is the phase difference between the driving force and the displacement in a forced oscillation at resonance?

Step 1: Understand what forced oscillation means. It is when an external force is applied to a system to make it oscillate.
Step 2: Learn about resonance. Resonance occurs when the frequency of the driving force matches the natural frequency of the system.
Step 3: Know that at resonance, the system oscillates with maximum amplitude.
Step 4: Recognize that the driving force and the displacement of the system are related in terms of their phase.
Step 5: At resonance, the driving force and the displacement are perfectly in sync.
Step 6: This means that there is no delay between the driving force and the displacement.
Step 7: Therefore, the phase difference between the driving force and the displacement at resonance is 0 degrees.
