The bulging of earth at the equator and flattening at the poles is due to __ *
A. Centripetal force
B. Centrifugal force
C. Gravitational force
D. Electrostatic force
Answers
Answer:
The bulging of the equator and flattening at the poles is due to the rotation of the Earth. The Earth rotation creates the centrifugal force which is the pseudo effect counter. It balances the centripetal force that acted in inward direction.
The term centrifugal force, it is that force which is perpendicular to the axis of the Earth on excluding the equator. It’s not opposite to gravity but it gives a vector component towards the equator.
The term pseudo force is that force which acts to the overall mass whose motion is described by the non-inertial frame. The pseudo force is also known as the inertial force. It satisfied Newton's law of motion.
The pseudo effect pushes the earth outwards, bulging form the Earth and flattening at the poles.
So, the option (B) is correct.
The bulging of the earth at the equator and flattening at the poles is due to b) centrifugal force.
Explanation:
The bulging of the equator and poles to be flattened is due to the rotation of the earth.
The rotation of the earth creates the centrifugal force which is the pseudo effect counter.
In an inward direction, it balances the centripetal force that acted.
While it rotates, the earth has poles that are flattened because of the centrifugal force that acts on its poles.
Because of the great speed, near the poles flattening of the surface rises.
