Solve the all parts of given problem:
Problem: A third charge of +8.00nC is placed in problem 2) 5 cm south of origin.
Part A: What would be the electric force (magnitude and direction) at this point? Draw a picture of this situation showing the electric forces and their resultant vector.
Part B: What would be the electric force of these three charges at 4 cm north of origin? Draw a picture of this situation showing the electric field and the resultant vector direction.
