Question: A forced oscillator has a mass of 3 kg and is driven by a force of 12 N at a frequency of 2 Hz. What is the amplitude of the oscillation if the damping coefficient is 0.1 kg/s?

Options:

1. 0.1 m
2. 0.2 m
3. 0.3 m
4. 0.4 m

Correct Answer: 0.2 m

Solution:

Using F = mAω², we find A = F / (mω²) = 12 / (3*(2π*2)²) ≈ 0.2 m.
