Two tiny spheres of mass = 4.80 carry charges of equal magnitude, 72.0 , but opposite sign. They are tied to the same ceiling hook by light strings of length 0.530 . When a horizontal uniform electric field that is directed to the left is turned on, the spheres hang at rest with the angle between the strings equal to in the following figure.
