Asked by Alexa
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

Eq sin 30 = mg (make sure to change mass to kg). Find E. Now Eq cos 30 = T. A Free Body Diagram is most helpful in this problem.
