1. The problem statement, all variables and given/known data Point P is collinear with a +2.80 μC charged particle and a -8.50 μC charged particle as shown in the diagram below. Point P is 10 cm to the left of the positive charge and 20 cm to the left of the negative charge. What is the electric field at point P? p--------(2.80uc)---------(-8.50uc) 2. Relevant equations e=kq/r^2 3. The attempt at a solution i found the e field from p to the positive charge and p to the negative charge should i add them to find the total e field at point p?
