Explanation:

Assuming that the balances are symmetrical and the center of mass is at the center of the balances, the reading of the upper balance would be 1 kg as well. This is because the gravitational force acting on the system is balanced and the net force acting on each balance is zero, resulting in an equal reading on both balances.
