Answer:

Since there is more centrifugal force at the equator to cancel gravity, your overall weight at the equator versus at the poles is even less. The centrifugal force on your body at the equator is 0.034 m/s2 times the mass of your body. The centrifugal force at the poles is zero.

Explanation:

Answer 2

Answer:

The Earth spins very fast, relative to its size.

Due to this, it bulges outwards slightly towards the centre.

So, the Earth's radius at the centre is more than that at the poles.

As gravity is inversely proportional to the distance², the weight at the equator is less than that at the poles.
