(a)Two charges are placed on the x-axis: one is placed at x = 3 m and the other is at x = −3 m. The magnitude of both charges is 8.1 μC but the blue one (at x = −3 m ) is positive while the red one ( at x = +3 m) is negative. What are the x - and y-components of the electric field at (x, y) = (0 m, +4 m) ? Ex = N/C Ey = N/C (b) Now the positive and negative charge switch places. The magnitude of the charges is still 8.1 μC where the blue one (now at x = +3 m ) is positive and the red one (now at x = −3 m) is negative. What are the x - and y-components of the electric field at (x, y) = (0 m, +4 m) ? Ex = N/C Ey = N/C
