## Homework Statement

Two point charges are placed on the y-axis. One is +3.0 C and located at position (0, 2 m), the other is -2.0 C and located at the origin. Use the diagram to find the magnitude and direction of the electric field and the force on a +1.0 x 10-9 C test charge placed in the following locations.

a. (0, 1.0 m)

b. (0, -2.0 m)

c. (1.0m, 0)

## Homework Equations

E= kq/(r^2)

## The Attempt at a Solution

So for part a:

F= (K(3x10^-6)/(1^2) + K(2x10-6)/(1^2))

E= F/(test charge)

Same for part b, but the radius is different.

My question is how do I get part C?

I calculated the force between the -2uc charge and point C, but how do I get the force between the +3uc charge and point C?

Do I need to find the angle?
