An object of mass m = 2.5 g and charge Q = +42 µC is attached to a string and placed in a uniform electric field that is inclined at an angle of 30.0° with the horizontal (FIGURE 19-50). The object is in static equilibrium when the string is horizontal. Find
(a) The magnitude of the electric field
(b) The tension in the string.
