A body is droppped in a hole drilled across a diameter of the earth. Show that it executes SHM. Assume the earth to be homogenous sphere.

A body is dropped in a hole drilled across diameter of the earth. Show that it executes SHM Asuume earth to be a homogenous sphere, find the time period of its motion. Given density of earth is 5.51 xx10^(3)Kgm^(-3) and G=6.67xx10^(-11)Nm^(2)kg^(-2)

If a hole is drilled along the diameter of the earth and you leave a coin in the hole, then

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

If hole is bored along the diameter of the earth and a stone is dropped into the hole then the stone

If a hole is bored along the diameter of the earth and a stone is dropped into hole
