An object of mass m = 2.9 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. the object is in static equilibrium when the string is horizontal.
a) find the magnitude of the electric field. b) find the tension in the string. i know a is -mg + sin 30 * qe =0 but i don't know how to solve for it
