Is the acceleration due to gravity different in south pole and north pole

Mohak Tandon Asks – “

“Is the acceleration due to gravity different in south pole and north pole?”

Answer:

As per theory, acceleration due to gravity changes with altitude, depth and latitude.

If we consider that the variation of g with latitude is caused by rotation of earth only, then the value of g will be same for both north pole and south pole.

But, the change in the value of acceleration due to gravity with latitude is caused by the shape of earth too. So it depends your distance from the centre of earth when you are at north pole or south pole.

For calculations the polar radius is taken same at North as well as south pole. So, value of g can be taken the same for both poles.

A Problem from gravitation

Soumya asked:

“A body of mass 5kg is taken on equitorial plane.
But due to some change earth’s diurnal motion, its
weight has become zero. What will be the length of
day now?”
