The angular velocities of three bodies in simple harmonic motion are ₁, ₂, ₃ with their respective amplitudes as A₁, A₂, A₃ If all the three bodies have same mass and velocity, then
Options
- AA₁^2 ₁^2=A₂^2 ₂^2=A₃^2 ^2
- BA₁^2 ₁=A₂^2 ₂=A₃^2 ₃
- CA₁ ₁^2=A₂ ₂^2, A₃ ₃^2
- DA₁ ₁=A₂ ₂=A₃ ₃
Correct answer
D. A₁ ₁=A₂ ₂=A₃ ₃
Step-by-step solution
Rate of change of displacement is known as velocity. The equation for displacment ( y ) of a body in SHM with angular velocity is given by y=a t where a is amplitude velocity v= rate of change of displacement = d y d t v= d y d t = d d t (a t)=a t Given, v₁=v₂=v₃ and a₁=A₁, a₂=A₂ . a₃=A₃A₁ ₁=A₂ ₂=A₃ ₃
