Gravitational force is maximum at which of the following place?
At poles
Effective gravity depends on two factors: distance from Earth's centre and the centrifugal effect of rotation. Earth's oblate shape makes the polar radius smaller than the equatorial radius, so \(g \propto 1/r^2\) is larger at the poles.
Rotation reduces apparent gravity most at the equator (largest centrifugal force) and not at all at the poles (zero rotational radius).
Both effects combine: \(g\) is maximum at the poles (≈9.832 m/s²) and minimum at the equator (≈9.780 m/s²).
