Answer 1

Dear student
as we know that the weight on the moon become 1/6 of the weight on the earth.
so as 12 kg is balancing it .it means both the blocks are 12 kg in weight and the reading of the spring balance is 12kg.
so at moon it will become 1/6
= $\frac{12}{6}$ = 2kg
reading shown by spring balance at moon = 2kg
