Question

Why value of g varies with place to place

Answer 1

It all has to do with the concentration of mass under you. The more mass, the greater the gravity. So, if you are "on" (the quotations are due to the fact that you can't actually "stand" on the surface of a gas-giant planet.... anyhoo) the surface of Jupiter, you will experience gravity many times stronger than anywhere on earth, due to Jupiter's being far more massive.

Even on earth, there are areas where gravity is fractionally stronger than in other areas. Again, it comes down to mass. Certain elements are more massive, and there is reasonable possibility that there is a heavier pocket of material in the mantle beneath you

Answer 2

Explanation:

The formula can be used to find the value of acceleration due to gravity is as follows :

$g=\dfrac{GM}{r^2}$

M is the mass of earth

r is the distance between object and the earth

It is clear form he above formula that the value of g depends on the distance from the center of earth. As the value of r varies for all objects, so the value of g varies with place to place. Hence, this is the required solution.
