Crushed phosphate ore consists of quartz and phosphate particles. when the mixture is vibrated, the quartz becomes negatively charged and the phosphate becomes positively charged. separation of the phosphate from the quartz is then achieved by passing the mixture vertically down through a pair of charged, parallel plates. the electric field between the plates is 5x105 v/m and the specific charge on the ore mixture is 1x103 c/kg. the ore particles must be separated by at least 100 mm at the bottom to be sorted into separate bins. (a) sketch a suitably labelled diagram of the situation, showing the path of the ore, the plates and collection bins (b) calculate the minimum length of the parallel plates to achieve a separation of 100mm.
