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

Text Solution

Verified by Experts

The acceleration of the partical always pointing towards center of earth and displacement of the partical is not proportional to displacement from earth surface hence the motion is not SHM as seen from earth surface.
