Homework Statement
http://loncapa.vcu.edu/res/vcu/phys202/zzImages/Ch25_TB.jpg
A charged ball with charge Q1 = 0.1 μC and mass 0.05 kg is suspended from a ceiling with a thin massless string as shown in the figure. The second charged ball has a net charge Q2 = -0.5 μC and it is located d = 0.3 m away from the suspended ball. What is the angle θ that the string makes with the vertical (dahsed vertical line) as shown in the figure? Provide your answer in degrees. (Note: The dashed horizontal line is not a string or rod, it only designates the distance d between the two spheres)
Homework Equations
F=(K*Q1*Q2)/ (d^2)
The Attempt at a Solution
I converted the charges to C first, getting 1e-7 and -.5e-7. Because the charges are attracting, I found that the force is equal to 5.6e-14, which would be my force in the x component. The y force component would be equal to F=mg, which is (.05 * 10). How would I go about finding the angle with these 2 values?
