Why the value of acceleration due to gra...

Why the value of acceleration due to gravity is more at the poles than at the equator?

Text Solution

Verified by Experts

As `g = (GM)/(R^(2))`, where `M` is the mass and `R` is the radius of earth. The value of `R` is more on equator than at pole. Hence `g` at pole is greater then `g` at equator.
