Once again you stumble upon a charged pith ball in a uniform electric eld, shown in the picture below. The magnitude of the pith ball's charge is 1 nC, the string holding the pith ball makes an angle 6 = 20 degrees with the vertical, and the electric eld points at an angle cp = 10 degrees below the horizontal. The pith ball is stationary and the string is carrying a tension of 3 N. Be careful with your trig on this problem! A. Is the pith ball's charge positive or negative? Explain. [Hint You'll probably need a force diagram] B. What is the magnitude of the electric eld? [Hintz What does Newton's second law tell you about the horizontal components of the forces?] C. What is the mass of the pith ball? [Hint What does Newton's second law tell you about the vertical components of the forces?) Solve the problem using good problem solving procedures before you check the solution (below). Once you have done this make any necessary corrections. See the Canvas rubric attached to this assignment as a reminder about expectations when doing corrections
