Three charged marbles are glued to a nonconducting surface and are placed in the diagram as shown. The charges of each marble are $q_1 = 5.50 \ \mu C$, $q_2 = 1.18 \ \mu C$, and $q_3 = -1.63 \ \mu C$. Marble $q_1$ is a distance $r_1 = 3.00 \ cm$ to the left of the marble $q_2$, while marble $q_3$ is a distance $r_3 = 2.00 \ cm$ to the right of the marble $q_2$, as shown. Calculate the magnitude of the electric field a distance $r' = 1.00 \ cm$ to the left of the center marble.

What is the electric field due to each individual marble? How do you find the total or "net" electric field when you have several electric fields? N/C
Another marble is placed 1 cm to the left of the middle marble. If this new marble has a charge of $-3.84 \ \mu C$, calculate magnitude and direction of the force on it.
magnitude 226.416
direction left
If you know the electric field how do you calculate the force on a charge in that electric field? Did you convert all of your values to SI units (meters, kilograms, coulombs, seconds)? N
