It is well known that the radius of earth at equator is more than radius at poles To estimate this let s assume two tunnels in earth 1 along the axis of rotation of earth and 2 along equatorial radius Both are filled with liquid Assuming earth s angular velocity as radius at equator is density of fluid as p find the difference in length of liquids in both tunnels in steady state Assume R g FR4 2 R4 R4 4 R4
