Question

Four charges are situated as shown in the diagram (each grid line is separated by 1 meter). All of the charges have a charge of +4 ?C (+4?10-6 C) EXCEPT the upper right charge is -3 ?C (-3?10-6 C) .

1) What is the magnitude of the net electric field at the point (0, 0)?

2) What is the direction of the net electric field at the origin?

3) what is the net work needed to bring in all four charges from infinity to build this configuration?
