Oscillations - Result Question 30

33. In a simple harmonic motion, when the displacement is one-half the amplitude, what fraction of the total energy is kinetic?

[1996]

(a) 0

(b) 14

(c) 12

(d) 34

Show Answer

Answer:

Correct Answer: 33. (d)

Solution:

  1. (d) Total energy of particle executing S.H.M. of amplitude (A).

E=12mω2A2

K.E.of the particle

=12mω2(A2A24)(. when .x=A2)

=12mω2×34A2=12×34mω2A2

Clearly, KE Total Energy =34
