I know you can resolve the components of force on the tension of the string to find the horizontol component. But how do you get from the components of tension to the tension?

Not really sure what do you mean “how do you get from the components of tension to the tension”. In fact, we do not need to find tension to find F = mg tan(6.0°). . After you have written down the component of tension and equate them to the weight and electrostatic force respectively to form 2 equations, you can divide the equations to eliminate tension and find F = mg tan(6.0°).
