MCQ: which one is heavier.?

Question

MCQ:
Left side of the physical balance you put "1 kg weight"
Right side of the physical balance you put "1000 g cotton"

a) both are equal
b) Left side heaveir
c) Right side heaveir
d) None of above

Answer 1

option c

Answer 2

I think we can have a deeper technical analysis of the situation we have. If we assume that the weighing machine is extremely precise and that 1000gm of cotton forms a heap of some height on the balance while the weighing bar on left balance is sufficiently thin, then the correct answer should be (b) i.e. the left side will be heavier. This is because the balance actually measures the weight of the object which is mass multiplied by the acceleration due to gravity at that point. The accn due to gravity on earths surface is 9.81 meter per sec square and its decreases as we go above the surface of the earth. so for the left side, the weight recorded is mass of the weighing bar * 9.81 = 1*9.81 = 9.81 newtons, but for the 1000gm cotton since it will be of some finite height, the accn due to gravity will be different at different points, infact it will be less that 9.81 at all points above the ground. So the true weight of the cotton recorded will be less that 9.81 newtons because of the lesser "net accn due to gravity". And hence the left side will be heavier. Well, was that too geeky!! :)

Answer 3

well.. both have equal amounts of Mass..

and the scale would not be able to tell the difference.

however, one is denser than the other...
the way we measure weight is multiply amount of Mass by acceleration of gravity, so, the weight is 1000 gm, = 1kg.. of mass times 9.81 m/s^2

Answer 4

A. 1kg=1000g.Dosen't matter whether the item is cotton or steel,both are the same weight.

Answer 5

A EQUAL

Answer 6

both are equal .
