Question

How is weight affected when initially the body is weighed in Delhi with a spring balance and the body is taken to moscow

Answer 1

W is equal to mg, where m is the mass and g is the acceleration due to gravity. Acceleration due to gravity (g) varies from place to place depending on a variety of factors. E.g.: At the poles the g is more at the poles and lesser at the equator.
Moscow is more towards the pole so the weight of a body measured is Moscow will be more than that measured in Delhi.
