Solve the all parts of given question:
Question 1: Two particles having charges of 0.550nC and 4.95nC are separated by a distance of 1.90m.
Part A: At what point along the line connecting the two charges is the net electric field due to the two charges equal to zero?
Part B: Where would the net electric field be zero if one of the charges were negative? Enter your answer as a distance from the charge initially equal 0.550nC.
Rework your solution from the beginning and check each step carefully.
