Three point charges (A =2.2 μC, B = 7.5 μC, C = -3.9 μC) are located at the corners of an equilateral triangle.

a. Find the direction and strength of the electric field at the location of charge A again but this time find by adding the electric field from individual charges. Compare your answer to the answer you got for problem 2. NOTE: when finding the electric field at the location of charge A you do NOT add the electric field of charge A at that point. Just think about the contribution of charges B & C.

b. Find the direction and strength of the electric field at the location of charge B.

c. Again, but now for the location of charge C.
