1. The problem statement, all variables and given/known data Two particles having charges q1 = 0.600 nC and q2=5.50 nC are separated by a distance of 1.10 m. At what point along the line connecting the two charges is the total electric field due to the charges equal to zero? 2. Relevant equations Coulomb's Law 3. The attempt at a solution i have no clue. I know that d = 1.10m. But how do I start the problem. Any suggestions would be nice..thanks in advance.
