Two charged particles are fixed on the x-axis 11 cm apart. The one on the left has a net charge of +25uc and the one on the right has a net charge of -15uc. What is the magnitude of the electric field 15 cm to the right of the negative charge?

Question

How do you solve this problem?

Thanks!

Answer 1

you can add them:

E=k(+25E-6/.26^2 -15E-6/.15^2)
