Since, weight of an object is the product of mass of the object and the value of acceleration due to gravity.
In Delhi, the weight of the object is equal to the product of mass of the body and the value of acceleration due to gravity in Delhi.
If this object is taken to the poles, then the weight of the object will increase and if it is taken to the equator, then its weight will decrease, as the value of acceleration due to gravity increases as we go from equator to the poles.
