Oscillations - Result Question 2

3. Average velocity of a particle executing SHM in one complete vibration is:

[2019]

(a) $\frac{A \omega}{2}$

(b) $A \omega$

(c) $\frac{A \omega^{2}}{2}$

(d) zero

Show Answer

Answer:

Correct Answer: 3. (d)

Solution:

  1. (d) Displacement of the particle in one complete vibration is zero, so, average velocity in one complete vibration will be

$=\frac{\text{ Displacement }}{\text{ Time interval }}=\frac{y_f-y_i}{T}=0$
