You are working with the following piece of code to produce a visual of the electric field from multiple charges. You are not sure yet if it is working properly or not. b) What is the purpose of Line 32 in code? ( E tot =E tot +E ) The electric field is being totaled up for each iteration of the for-loop so that by the end we will have the total electric field at all observation points at once. The electric field is being reset for the next calculation for the field from a different source of charge. The electric field is being totaled up for each iteration of the for-loop so that by the end we will have the sum total electric field from all sources of charge. The electric field is being reset for the next calculation for the field at a different observation location. Tries 1/2 Previous Tries
