$E = k \frac{ Q }{r ^{2} }$ Calculate that for each point charge. Then we'll add the vectors.

the answer is in degrees? I need how to find the angle

The direction of an electric field is the direction of the force on a positive test charge placed in the field. In this case the field is directed away from each of the positive charges.

The whole purpose of Openstudy is to surpass the inadequacies of current internet education by expounding concepts to people personally and helping their unique problems. Now that openstudy has been established, any less than that is a failure on the educators' parts.

Vector addition is simple- put the end of one on the point of the other (in any order), and take the final result.|dw:1346438644261:dw| Think of a parallelogram

The length of the arrows= the values in the equations above.
