Physics question--finding the magnitude of the electric field 1. The problem statement, all variables and given/known data A charged insulating ball of mass 7.0g with a uniform charge of 1.5mC hangs from a light thread inclined at an angle of 8 degrees to the vertical. Calculate the magnitude of the electric field. 2. Relevant equations q=mg/e e= Fe/q 3. The attempt at a solution I tried to use e=mg/q and i kept getting the wrong answer. Im not sure how or if i should use the given angle.Im confused because i dont know which formula i need to use for this question.
