Question

in which part of earth their is less gravitational force​

Answer 1

hey mate

at the equator line the gravitational force is less

Answer 2

The gravitational force above the Earth's surface is proportional to 1/R2, where R is your distance from the center of the Earth. The radius of the Earth at the equator is 6,378 kilometers, so let's say you were on a mountain at the equator that was 5 kilometers high (around 16,400 feet). You would then be 6,383 kilometers from the Earth's center, and the gravitational force would have decreased by a factor of (6,378 / 6,383)2 = 0.9984. So the difference is less than 0.2%.

Finally, there are very small differences (on the order of 0.01% or less) in gravity due to differences in the local geology. For example, changes in the density of rock underneath you or the presence of mountains nearby can have a slight effect on the gravitational force.
