The figure shows two snapshots of a single wave on a string. The wave is
traveling to the right in the +x direction. The solid line is a snapshot of the wave
at time t=0 s, while the dashed line is a snapshot of the wave at t=0.48s.

The signs of the charges are indicated explicitly such that ∣∣+q∣∣∣∣+Q∣∣=∣∣−q∣∣==∣∣−Q∣∣=qQ Four unique setups of charges are displayed. By moving one of the direction drawings from near the bottom to the bucket beside each of the setups, indicate the direction of the net electric force on the charge with magnitude Q, located near the center, else indicate that the magnitude of the net electric force is zero, if appropriate.arrow_forwardA number of electric charges has been placed at distinct points along a line with separations as indicated. Two charges share a common magnitude, q (lower case), and another charge has magnitude Q(upper case). The signs of the charges are indicated explicitly such that ∣∣+q∣∣∣∣+Q∣∣=∣∣−q∣∣==∣∣−Q∣∣=qQ Four different configurations of charges are shown. For each, express the net electric force on the charge with magnitude Q (upper case) as F⃗E=FE,xî where the positive x direction is towards the right. By repositioning the figures to the area on the right, rank the configurations from the most negative value to the most positive value of FE,x.arrow_forward
