My question is based on the weight and mass of object on equator and poles of earth .

Expert Answer:

the radius of earth at poles is : 6353 km
and at equator it is: 6384
 
due to this lowered radius the acceleration due to gravity will increase near poles and thus the same object would weigh more.
g = GM/R2
the rest of the question is self explainatory.
 
However i would like to add that there is one more very major reason for a weight change which we have not considered.
It is due to the earths rotation.
The earth's rotation causes a centripetal force which decreases the weight of objects on earth near the equator.
