A charge Q = -16.60 AC is fixed in place at y = 43.50 cm on the y-axis as shown in the diagram below. A second charge Q2 = 10.10 MC is fixed in place at x = 43.50 cm on the x-axis as shown in the diagram below. V Q1 X O Q2 1 pt What is the magnitude of the electric field at the origin, O (in N/C)? 2. AO 4.44 x 105 BO 5.02 x 105 CO 5.67 x 105 DO 6.41 x 105 EO 7.24 x 105 FO 8.18 x 105 GO 9.24 x 105 HO 1.04 x 106 1 pt If the sign of charge Q, is changed, the magnitude of the electric field at the origin will: 3. AO increase BO decrease CO remain unchanged
