The weight of a 0.7 kg object of charge Q is just balanced by another object of equal but opposite charge fixed to a support 132 cm above it. What is the magnitude of the charge Q (in μC)? [Note that 1 μC=1x10-6C.] Ok I know how to do this but it says I'm wrong... am I really wrong or is the computer wrong? .7kg times gravity = 6.86N The force between these two objects would be coulombs law. F= Ke (QQ/r^2) set force = to 6.86 and solve for Q It gave me .36443 micro C. What do you guys get?
