What is gravity at north pole, South pole and at different point on the equatorial regions. Give reasoning for your answers why do you think it is different or same. Can you imagine same concept for the electric charge, yes or No

Gravity at different points on Earth's surface can slightly vary due to the shape of the Earth, its rotation, and the distribution of mass across the planet. The force of gravity is stronger at the poles (the North Pole and the South Pole) and weaker at the equator for a few reasons.

1. Shape of the Earth: The Earth is not a perfect sphere; it is an oblate spheroid, meaning it is slightly flattened at the poles and bulges at the equator. This means that when you're at the poles, you're closer to the Earth's center, where gravity is stronger. Conversely, at the equator, you're farther away from the center, so gravity is weaker.

2. Centrifugal Force: Due to Earth's rotation, there's a centrifugal force that acts outwardly away from the axis of rotation. At the equator, the centrifugal force is the greatest because the speed of rotation is fastest there. This force effectively reduces the gravitational pull experienced by objects. At the poles, there is no centrifugal force acting outward because they are on the axis of rotation, so the full force of gravity is felt.

Therefore, theoretically, gravity is strongest at the poles and weakest at the equator. However, variations in terrain and the density of the Earth's crust can also cause localized gravitational anomalies.

Regarding the concept of electric charge, while there are similarities in how both gravitational and electric forces can act over a distance, there are key differences. Gravitational force is always attractive, while electric force can be both attractive and repulsive because there are two types of charge, positive and negative. Additionally, gravity is a fundamental interaction that only depends on mass and distance, whereas electric force depends on the type and amount of charge, as well as distance.
