JEE Mains · Physics · STD 11 - 13. oscillations

The displacement of a particle, executing simple harmonic motion with time period \(T\), is expressed as \(x(t)= A \sin \omega t\), where \(A\) is the amplitude. The maximum value of potential energy of this oscillator is found at \(t=T / 2 \beta\). The value of \(\beta\) is ___________.

  1. A 1
  2. B 2
  3. C 4
  4. D 8
Verified Solution

Answer & Solution

Correct Answer

(B) 2

Step-by-step Solution

Detailed explanation

Potential energy is maximum at extreme position The particle starting at mean position reaches extreme position in time \(\frac{ T }{4}\). So \(T/2\beta = T/4 \Rightarrow 2\beta = 4 \Rightarrow \beta = 2\)
