1. [-12 Points] DETAILS SERCP11 15.3.P.021. MY NOTES I | ASK YOUR TEACHER Charge q1 = 2.00 nC is at x1 = 0 and charge q2 = 6.50 nC is at X2 = 2.50 m. At what point between the two charges is the electric eld equal to zero? (Enter the X coordinate in m.) 2. [-12 Points] SERCP11 15.3.P.024. ASK YOUR TEACHER | (a) Three point charges, A = 1.80 uC, B = 6.60 uC, and C = 3.95 uC, are located at the corners of an equilateral triangle as in the figure above. Find the magnitude and direction of the electric field at the position of the 1.80 uC charge. magnitude N/C direction below the +x-axis (b) How would the electric field at that point be affected if the charge there were doubled? The magnitude of the eld would be halved. The field would be unchanged. The magnitude of the field would double. The magnitude of the eld would quadruple. Would the magnitude of the electric force be affected? Yes NO 3. [-/2 Points] DETAILS SERCP11 15.A.P.058.MI. MY NOTES ASK YOUR TEACHER A small plastic ball of mass m = 1.00 g is suspended by a string of length L = 17.0 cm in a uniform electric field, as shown in the figure below.
