Two small spheres, each of mass 4.00 g, are suspended by light strings 10.0 cm in length. A uniform electric field is applied in the x direction. The spheres have charges equal to -2.00 multiplied by 10^-8 C and +2.00 multiplied by 10^-8 C. Determine the electric field that enables the spheres to be in equilibrium at an angle of θ = 15.0°.
Here is a link to the image:

m1 = 4.00g
m2 = 4.00g
θ = 15.0°
I thought I might use E = (k|q||q|)/r²
I'm confused about the charges on the two spheres. How are they apart if they have opposite charges? Shouldn't it be that only like charges can repel and be in equilibrium?
Any help would be great to get me started.Thank you.
