Mate that is because the scale moves up slightly when you do that trying to returen to equalibrium these rods are fixed. yes i do physics Lets just focus on it being over!

it must change becuase there is a force between them to attract one another only small amounts but it does change. Y else would the weight change?

ye but then u can't because the current is 0 in the formular doesn't work, hate questions when they don't ask them right. I recon it was a fare exam through was a well writen one over all!

For the question that asks the distance between the rod, if the mass they gives you decreases with the increase in current doesn't that mean the distance is changing as a result of the second rod being atracted to the first?
