Vedclass · Answer

(C) The weight of an object is given by $W = mg$,where $m$ is the mass and $g$ is the acceleration due to gravity.Since $g$ is greater at the poles than at the equator,the weight of an object is higher at the poles.$A$ spring balance measures the weight $(W)$ of an object,which varies with the location due to the change in $g$.If you purchase goods at the equator using a spring balance,you get a certain mass for a specific weight reading.When you take these goods to the poles,the same mass will show a higher weight reading on a spring balance.However,a beam balance compares the mass of the object with a standard mass (counterweight),which is unaffected by the change in $g$ because $g$ acts equally on both sides of the balance.Therefore,to gain an advantage,one must use a spring balance to measure weight at the equator and sell it at the poles,as the spring balance will show a higher value at the poles for the same mass.

It is found that the 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 at the poles,provided:

Similar Questions

An object has a mass of $30 \ kg$. What is its weight $(i)$ on the moon $(ii)$ on another planet? The value of $g$ on the moon is $1/6$ the value of $g$ on the earth. The value of $g$ on the planet is $3$ times the value of $g$ on the earth. Take $g_{earth} = 10 \ m/s^2$.

It is said that the mass of an object remains constant at all places,while its weight may change. Why?

The weight of any person on the moon is about $1/6$ times that on the earth. He can lift a mass of $15\, kg$ on the earth. What will be the maximum mass,which can be lifted by the same force applied by the person on the moon (in $, kg$)?

At some place on the equator,a bag of sugar weighs $W \ kg$. Will it weigh the same,more,or less when taken to Antarctica? Give a reason for your answer.

Show that the weight of an object on the moon is one-sixth of its weight on the earth. [Given: mass of earth $= 5.98 \times 10^{24} \ kg$,mass of moon $= 7.36 \times 10^{22} \ kg$,radius of earth $= 6.37 \times 10^{6} \ m$,radius of moon $= 1.74 \times 10^{6} \ m$]
