Question 200: Gravitation

Question

Suppose that the angular velocity of rotation of earth is increased. Then, as a consequence :

Accepted Answer

With rotation of earth the effect  on acceleration due to gravity  vary as
g' = g $$-$$ $$\omega $$
2
R cos
2
$$	heta $$
Here $$	heta $$ is lattitude.
At poles $$	heta $$ = 90
o
so those will be  no change in gravity.
At all other point $$\omega $$ will increase so g' will decrease.

Answer

Weight of the object, everywhere on the earth, will increase.

Answer

Weight of the object, everywhere on the earth, will decrease.

Answer

There will be no change in weight anywhere on the earth.

Answer

Except at poles, weight of the object on the earth will decrease.
