Vedclass · Answer

(A) The acceleration due to gravity $g$ on the surface of the Earth is given by the formula $g = \frac{GM}{R^2}$,where $G$ is the gravitational constant,$M$ is the mass of the Earth,and $R$ is the radius of the Earth.Because the Earth is not a perfect sphere but is flattened at the poles and bulges at the equator,the radius $R$ is maximum at the equator and minimum at the poles.Since $g \propto \frac{1}{R^2}$,the value of $g$ is inversely proportional to the square of the radius.Therefore,$g$ is minimum where $R$ is maximum,which is at the equator.Thus,the force of gravity is least at the equator.

What is the effect on the value of $g$ at the equator if the Earth stops its rotation?

$A$ planet has the same density as that of the Earth,and the universal gravitational constant $G$ is twice that of the Earth. The ratio of the acceleration due to gravity on the planet to that on the Earth is:

Assume that a tunnel is dug through the Earth from the North Pole to the South Pole and that the Earth is a non-rotating,uniform sphere of density $\rho$. The gravitational force on a particle of mass $m$ dropped into the tunnel when it reaches a distance $r$ from the center of the Earth is:

The rotation of the Earth,having radius $R$,about its axis speeds up to a value such that a man at latitude angle $60^{\circ}$ feels weightlessness. The duration of the day in such a case is:
