That is half up diameter. Equal toe. Five centimeter are We can write this as five times 10 to the power minus two Neto and current for Angel. Okay, Bo is 1 25 and Pierre And you want to calculate the potential difference across this killer away using homes and Ivy Hill, we icicle toe higher times are And we asked her what relation for our that are equal to resist duty Times Lind upon idea off position. So by putting the way you off our here we get being equal toe Hi terms resistant gene times lend upon any opposition We asked her that area position Equal toe bye indoor So get off radius So we heal re It will too. I don't row a bomb Bye are scared Nobody Paula Deen Different values in the relation we equal to here Currencies 1 25 in Pierre and uh resisted you for couples 1.72 times 10 to the power minus and want me to lend off the families. 100 times tend to the bar. What's E meter? A bond pie is stripping 14 times your radius off. Cable is five times tend to the bower minus two meter. So by computing, all these university get would dish equal to doing to seven point four. I won't their son so
