**[SOLVED] ELECtric Field Problem PLEASE HELP ! HELP!**

## Homework Statement

Two particles are fixed to an

**x axis:**

**particle 1 of charge q1 = +2.8*10-8 C at x = 20 cm and**

**particle 2 of charge q2 = -4.50q1 at x = 70 cm.**At what coordinate on the axis is the net electric field produced by the particles equal to zero?

Do not convert to meters. leave the answers in cm. so we are trying to find the x-coordinate.

i really have no clue where to start.

**Relevant equations**

E= kQ/ R^2
