Asked by Rachel
An object of mass m= 4.8g and charge Q = 49uC is attached to a string and placed in a uniform electric field that is inclined at an angle of 30.0 with the horizontal (see the figure). 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
