if a boby is released into a tunal dug across the diameter of earth, it executes simple harmonic motoin with time period

If a body is executing simple harmonic motion, then

Define time period of simple harmonic motion.

For a particle executing simple harmonic motion, the acceleration is proportional to

Assume that a tunnel is dug along a chord of the earth, at a perpendicular distance (R//2) from the earth's centre, where 'R' is the radius of the Earth. The wall of the tunnel is frictionless. If a particle is released in this tunnel, it will execute a simple harmonic motion with a time period :

Explain by plats the position of particle executing simple harmonic motion at different time.
