From there the equation could be rearranged to give D as the subject.
D = KI1I2L / mg
I cant remember exactly how it went but from there looking at the table that was given ,take a...
Yeh thats what i got also... at first i looked at it and was thinking... how could it be so much less energy, but the i realized that as the radius increased, the amount of energy was reduced significantly :) I hope thats right cause thats what i got. I did it a bit differently though where i...
