Wave Mechanics Question 545

Question: Suppose a tunnel is dug along a diameter of the earth. A particle is dropped from a point, a distance h directly above the tunnel, the motion of the particle is

Options:

A) simple harmonic

B) parabolic

C) oscillatory

D) non-periodic

Show Answer

Answer:

Correct Answer: C

Solution:

[c] When a particle is dropped from a height h above the centre of tunnel.
(i) It will oscillate, through the earth to a height h on both sides. (ii) The motion of particle is periodic. (iii) The motion of particle will not be S.H.M.
