Q9 of 61 Page 318

It is found that weight of an object is more at the poles than at the equator. So it is beneficial to purchase goods at the equator and sell them a the poles, provided:

Since weight of object is more at poles than at the equator, so it is beneficial to purchase goods at equator and sell at poles provided a spring balance is used as a spring balance measures the weight of an object whereas equal beam balance measures mass and mass is constant and does not change from place to place.


Hence option B is correct.
