Charged beads are placed at the corners of a square in the various configurations shown in

(Figure 1) . Each red bead carries a charge +q, and the blue bead carries a charge −q.

Rank the configurations according to the magnitude of the electric field at the center of the square, largest magnitude first.

Answer :

Answer:

The consecutive charge configuration has a more intense field than alternating

Explanation:

In each corner we place a different account there are only two different settings, see attached.

In the case of alternating charging (+ - + -) see diagram 1, the electric field in the center is canceled in pairs, resulting in a zero field

In the case of consecutive loads (+ + - -) in this case we have a result between the two charges, therefore the total field is

          E = 2 k q / ra2 a cos 45

The consecutive charge configuration has a more intense field than alternating
