Q74 / 90 · JEE Main 2024 (29 Jan Shift 2) · Physics

A simple harmonic oscillator has an amplitude A and time period 6π second. Assuming the oscillation starts from its mean position, the time required by it to travel from x=A to x=32A will be πx s, where x=_______.

Correct answer: 2

Solution

Figure

From phasor diagram particle has to move from P to Q in a circle of radius equal to amplitude of SHM.

cosϕ=3 A2 A=32

⇒ϕ=π6

Now, π6=ωt

⇒π6=2πTt

⇒π6=2π6πt

⇒t=π2

So, x=2

Hence, the correct answer is 2.
