Compute each part of given question:
Question: A plastic ball has a charge of 3.00 µC and is attached to a string. When the ball is placed in a uniform horizontal electric field, the string makes an angle of 17.0° with the vertical and has a tension of 0.415 N.
Part A: What is the mass of the small plastic ball?
Part B: What is the strength of the electric field?
I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks.
