Questions
A particle is subjected to two simple harmonic motions in the same direction having equal amplitudes and equal frequency. If the resulting amplitude is equal to the amplitude of individual motions, the phase difference between them is
detailed solution
Correct option is B
Amplitudes are equal,A1=A2=A3 ; Anet=A resultant amplitude is Anet=A12+A22+2A1A2cosθ A=A2+A2+2A2cosθ A2=2A2+2A2cosθ 2A2cosθ=-A2 cosθ=-12,⇒θ=120∘ θ=2π3Talk to our academic expert!
