AP EAMCET · PHYSICS · Oscillations
A simple harmonic oscillation is represented by \(x=A \cos \left(\omega t+\frac{\pi}{4}\right)\). Its speed is maximum when \(t\) equals
- A \(\frac{\pi}{2 \omega}\)
- B \(\frac{\pi}{4 \omega}\)
- C \(\frac{\pi}{\omega}\)
- D \(\frac{2 \pi}{\omega}\)
Answer & Solution
Correct Answer
(B) \(\frac{\pi}{4 \omega}\)
Step-by-step Solution
Detailed explanation
Given that, equation of a particle executing Simple harmonic motion is \[ x=A \cos \left(\omega t+\frac{\pi}{4}\right) \] Now, velocity of particle, \(v=\frac{d x}{d t}\)…
