A body weighs more at poles than at the equator of earth. Why ?

Text Solution

Verified by Experts

(i) The weight of an object is defined as the force with which the earth attracts the object. It is given as ,
W=F=mg
(ii) The weight of an object depends on the mass of the object and the value of acceleration due to gravity
(iii) On the surface of the earth , the value of g is highest at the poles and decreases slowly with decreasing latitude becoming lowest at the equator .
Hence, a body weighs more at the poles and less at equator .
