Imagine a tunnel dug along a diameter of the earth. Show that a particle dropped from one end of the tunnel executes simple harmonic motion. What is the time period of this motion? Assume the earth to be a sphere of uniform mass density (equal to its known average density=5520 kg m^(-3) .)G= 6.67xx10^(-11)Nm^(2)kg^(-2) .Neglect all damping forces.

Suppose a tunnel is dug along a diameter of the earth. A particle is dropped from a point at a distance h directly above the tunnel. The motion of the particle as seen from the earth is
