Question
Two point charges of unknown mass, one of charge Q1=10.0 nC (gold color in the diagram) and one of charge Q2=15.0 nC (purple in the diagram), hang from two strings as shown in the figure (strings
match the color of their hanging charge). The length of the left (gold) string is L1=1.74 m and the length of the right (purple) string is L2=2.00 m. String L1 makes an angle of 0₁= 20.0⁰ with the vertical
(angle shown in gold on the diagram). String L2 makes an angle of 0₂= 35.0° with the vertical (angle shown in purple on the diagram). The entire region is exposed to a horizontally-pointing Electric Field, E,
shown in light blue on the diagram, whose magnitude is 1.00e+03 N/C. The charges hang at exactly the same height.
