Oscillations question

2019 · Q137

NEETPhysicsOscillationsMCQ+4 / −1
The radius of circle, the period of revolution, initial position and sense of revolution are indicated is the figure. NEET 2019 Physics - Oscillations Question 18 English

y- projection of the radius vector of rotating particle P is :
  1. A
    y(t) = 4sin(πt2)\left( {{{\pi t} \over 2}} \right)(2πt​), where y in m
  2. B
    y(t) = 3cos(3πt2)\left( {{{3\pi t} \over 2}} \right)(23πt​), where y in m
  3. C
    y(t) = 3cos(πt2)\left( {{{\pi t} \over 2}} \right)(2πt​), where y in m
  4. D
    y(t) = -3cos2π\piπt, where y in m

Correct answer: C

Angular velocity, (ω\omega ω) = 2πT=2π4=π2{{2\pi } \over T} = {{2\pi } \over 4} = {\pi \over 2}T2π​=42π​=2π​ rad/s

Since, at t = 0, displacement (y) is maximum, so equation will be cosine function.

y = a cos ω\omega ωt

⇒\Rightarrow⇒ y = 3 cos (πt2)\left( {{{\pi t} \over 2}} \right)(2πt​)
