(4%) Problem 25: A set of electric charges has been located at distinct points zlong 2 line with separations as indicated. Two charges share a common magnitude, g (lower case), and another charge has magnitude ) (upper case). The signs of the charges are indicated explicitly such that |+dl =|-d~=q |+Ql=|-Ql= [ & Four distinct setups of charges are presented. For each, express the net electric force on the charge with magnitude @ (upper case) as FrpFpgi where the positive g direction is towards the right. By repositioning the images to the region on the right, rank the setups from the maost negative value to the most positive value of Fig ;. most negative Fg . 5 L1 e @ +q +q +@Q . @ e +Q +q q [L -}L-l e @ q Q q L1 4 o 4 q +Q +q most positive Fg
