(14 points) On Earth, a 0.3 kg charged pith ball (labeled 1 in the diagram) is hanging from a string at an unknown angle of with respect to the vertical. A second charged pith ball (labeled 2 in the diagram) is fixed to a table such that it is 0.85 meters away from the first ball. The line between the two balls makes an angle of 30 degrees with respect to the horizontal. Both pith balls have identical +5.8 C charges. The system is in equilibrium. Model the pith balls as point charges. Note, the figure is not drawn to scale and is not 30 degrees. (a) What is the electric field created by the second charge at the location of the first charge? Using a standard coordinate system, express in cartesian components as . (b)Is this in stable or unstable equilibrium? Explain. (c)What is the angle, , the string makes with the vertical
