Q. At which of the following places Weight of a person will be maximum?
Answer: At Poles
Notes: The weight of a person is affected by the gravitational force acting on them, and it varies depending on their location on the Earth's surface. The weight of a person will be maximum at:
[A] At Poles
The reason for this is that the gravitational force is stronger at the poles compared to other locations on Earth. This is because the Earth is not a perfect sphere; it is slightly flattened at the poles and bulging at the equator due to its rotation. As a result, the distance from the center of the Earth to a person's position is shorter at the poles, leading to a greater gravitational force according to Newton's law of universal gravitation (F = G * (m1 * m2) / r^2), where 'F' is the force of gravity, 'G' is the gravitational constant, 'm1' and 'm2' are the masses of the two objects (in this case, the person and the Earth), and 'r' is the distance between them.
At the equator, the gravitational force is slightly weaker due to the greater distance from the center of the Earth caused by its bulging shape. Therefore, a person will weigh slightly less at the equator compared to the poles. The weights at the Tropic of Cancer and Tropic of Capricorn will be somewhere in between, closer to the equator but not as low as the equator itself.
