The answer to question number G 2 is below,
A beam balance works on the principle of ‘moment of force’.
If the mass of A and B are equal then the weights FA and FB will also be equal. Since, the support of the beam is at the middle, the moment of force (product of force and distance between the end and the middle of the beam) due to the two forces at the mid-point O will cancel each other and will be zero. In this case, the beam is balanced and hence we conclude that the two masses are equal.
If the mass of A is greater than B, then the moment due to force FA about O will be greater than the moment due to force FB about O. So, the beam will align downwards on the side of mass A.
