Weight of an object changes from place to plate on the surface of the Earth.

Explanation

i. The shape of the Earth is not exactly spherical. It is flattened at poles, while bulged at equator.
ii. Weight is the Earth's gravitational force acting on the object, which is generally `W=mg`.
iii. Mass of the object remains the same but value of g keeps on changing from place to place.
iv. The value of g is maximum at poles is `9.83m//s^(2)` while it is the least at equato i.e. `9.78m//s^(2)`.
v. Due to this the weight of an object changes from place to place on the surface of the Earth.
vi. It is maximum at poles but gets reduced at equator.
