# P the Weight of an Object is More at the Poles than at the Equator. is It Beneficial to Purchase Goods at Equator and Sell Them at the Pole? Does It Matter Whether a Spring - Physics

Short Note

The weight of an object is more at the poles than at the equator. Is it beneficial to purchase goods at equator and sell them at the pole? Does it matter whether a spring balance is used or an equal-beam balance is used?

#### Solution

The weight of an object is more at the poles than that at the equator. In purchasing or selling goods, we measure the mass of the goods. The balance used to measure the mass is calibrated according to the place to give its correct reading. So, it is not beneficial to purchase goods at the equator and sell them at the poles. A beam balance measures the mass of an object, so it can be used here. For using a spring balance, we need to calibrate it according to the place to give the correct readings.

Is there an error in this question or solution?
