Question

The bulging of earth at the equator and flattening at the poles is due to _______.

Options
  • Centripetal Force

  • Centrifugal Force

  • Gravitational Force

  • Electrostatic Force

Solution

The bulging of equator and flattening at poles is due to rotation of earth. The rotation of earth creates a centrifugal force which is pseudo effect counter balancing the inward acting centripetal force. This pseudo effect pushes the earth outward, bugling from earth, and flattening at poles. 
Hence correct answer is Centrifugal Force.
