The displacement of a particle executing simple harmonic motion is given by y = A₀ + A sinωt + B cosωt.
Then the amplitude of its oscillation is given by :
(1) A₀ + √(A² + B²)
(2) √(A² + B²)
(3) √{A²₀ + (A + B)²}
(4) A + B

The amplitude of its oscillation is given by

\bold{\sqrt{A^{2}+B^{2}}}

Step by step explanation:

"Simple harmonic motion in which restoring force is directly proportional to the displacement of the particle from the mean or equilibrium position."

From the given,

The displacement of a particle executing simple harmonic motion is given by

\bold{y=A_{o}+A\,sin\omega t+B\,cos\omega t}

y^{I}=y-A_{o}

\Rightarrow A\,sin\,\omega t+B\,cos\,\omega t

From the diagram, (in attachment)

R=\sqrt{A^{2}+B^{2}+2AB\,cos\,90^{o}}

 \Rightarrow \sqrt{A^{2}+B^{2}}

The amplitude of its oscillation is given by \bold{\sqrt{A^{2}+B^{2}}}.
