- The magnitude of the force between a pair of point charges is proportional to the product of the magnitudes of their charges and inversely proportional to the square of their separation distance. Four distinct charge-pair arrangements are presented. All charges are multiples of a common positive charge, q. All charge separations are multiples of a common length, L. Rank the four arrangements from smallest to greatest magnitude of the electric force.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.
