Answer: 1/256 s.
- A 1/256 s
- B 256 s
- C 1/128 s
- D 1/512 s
Correct answer: A. 1/256 s
Explanation: T = 1/f = 1/256 s ≈ 3.9 ms.
In SHM, displacement and velocity are 90° out of phase (v is maximum when x=0, and zero when x is extreme), while acceleration is always exactly opposite in sign to displacement, consistent with a = −ω²x.
Concept context
Simple harmonic motion, spring-mass, pendulum, energy in SHM, and resonance.
