## Homework Statement

The diagram shows the electric field lines surrounding three electric charges. Assume that q1 + q2 = -2.43 µC.

A) Calculate q2.

B) Calculate q1.

C) Calculate q3.

## Homework Equations

|Fe|= (k*|q1|*|q2|)/r^2

|E|=(k*|Q|)/r^2

k = 8.99*10^9 (N*m^2)/C^2

Fe = Electrostatic force between a pair of charges

r = charge separation

q1, q2 = charge magnitudes

E = electric field

Q = charged object

## The Attempt at a Solution

I am having a very hard time with this question. I'm not sure where to start. Based on the diagram I assume that q1 and q3 will be equal in charge and magnitude but am not sure where to go from here.

Any help would be greatly appreciated!
