1. Particle A is placed at position (3, 3) m, particle B is placed at (-3, 3) m, particle C is placed at (-3, -3) m, and particle D is placed at (3, -3) m. Particles A and B have a charge of -q and particles C and D have a charge of +2q. Assign values to q: A and B (-5C), C and D (+10C)

a) Draw a properly labeled coordinate plane with correctly placed and labeled charges

b) Draw and label a vector diagram showing the electric field vectors at position (0, 0) m

c) Solve for the magnitude and direction of the net electric field strength at position (0, 0) m
