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 [...]

Variation of acceleration due to gravity with depth. A doubt.

Rajkumar asks: “accelaration due to gravity decrease on depth of earth with the relation of g’=g(1-2h/R). but with relation of g=GM/(R*R)  g increase. Answer: When the object is on the surface or above it, the entire mass of the earth attracts it. But when it is inside, the net attraction towards CENTRE is provided only by the mass of [...]

Magnetism and Laws of motion

“Can a body at rest make another body move,according to the laws of Newton this is impossible. The question is in magnetism, If it happens then why is it not predicted by classical mechanics?” (Priyoranajn asked) Answer: First of all I congratulate you for your genuine thought. It is the critical thinking which will lead [...]
