Final answer:
A body will fall slightly faster at the polar region compared to the equator due to a stronger gravitational pull caused by Earth's smaller radius and greater mass density at the poles.
Step-by-step explanation:
If a body is dropped from the same height at the equator and polar region, it will actually fall slightly faster at the polar region. The reason behind this is that Earth is not a perfect sphere and has a bulge at the equator due to its rotation. This causes the radius of Earth to be about 30 km greater at the equator than at the poles. Gravity is inversely proportional to the square of the distance from the center of mass, so the gravitational pull is stronger at the poles where you are closer to the center of Earth. Hence, the correct answer is B. Polar region, due to stronger gravitational pull.
A body dropped near the surface of the Earth will fall with the same acceleration (neglecting air resistance), commonly denoted as 'g'. However, since 'g' varies slightly across the Earth's surface due to its shape and rotation, a body at the poles would experience a slightly stronger gravitational pull and hence fall faster as compared with the equator. The difference in gravity at the equator and poles further contributes to this effect.
In summary, while objects with different masses fall at the same rate in a vacuum, the slight differences in Earth's gravity due to its shape and rotation cause a body to fall faster at the poles than at the equator.
