Four identical small particles are charged to q = 20nC. They are all placed in the x-y plane at (0, 0, 0), (0, 2mm, 0), (2mm, 0, 0) and (2mm, 2mm, 0) respectively. A) What is the electric field E-> at (1mm,1mm,2mm) caused by particle q1(the one at (0, 0, 0))? Give your answer in terms of ˆi, ˆj, kˆ. B) What is the electric field E-> at (1mm, 1mm, 2mm) caused by all four particles? Give your answer in terms of ˆi, ˆj, kˆ. C)We place another small particle with mass m = 2g at (1mm, 1mm, 2mm). How much should it be charged in order to be able to hang suspended in the air?
