Consider the three charges shown in the figure. The magnitudes of the three charges are equal but they have different signs: Q 1 = -Q, Q2 =+Q, , Q3 =-Q, Q>0 The positions of the charges are shown, with Q1 on the positive y-axis, Q2 on the negative x-axis, Q3 on the positive x-axis, and Q2 and Q3 equal distance from the origin. Q1 is a different distance from the origin, a small change from the recitation. The magnitude of the electric field due to just charge Q1 at the origin (Point A), is E1 = 1,649 N/C. Let the distances be: 1 = 0.50 m and d = 0.28 m What is the magnitude of the total electric field, due to all three charges, at the origin, Point A? Give your answer in N/C to at least three significant digits to avoid being counted off due to rounding. 4 Q1,y = l B X A Q2 Q3 x = -d x = d
