Question

Two electric dipoles with charges +Q, where Q = 11.5 mC, are arranged as shown in the Figure. The charges +Q on the left are attached to each other by a rigid rod, and the two charges on the right are also rigidly attached to each other. Find the magnitude of the electric force between the two dipoles. https://media.cheggcdn.com/media/01d/01df42ce-9241-4695-a8cd-d32fd98f7299/phpZvNDqv.png The values ive tried are: 21160N,529000N,84640N,2116000N,1190250N,0N,1.5N,172.5N,34.5N,20250N, 86.25*10^-3N,8.4099*10^-4N,8.4099E-4N,-8.4099E-4N,8.434E-4N,750.03 N,25.45 N And none of them are right PLZ HELP

Explanation / Answer

D =sqrt(1.5^2+7.5^2) =7.649 m

F1 = 2*9*10^9*11.5*11.5*10^-6/7.5^2

=42320 N

F2 = 9*10^9*11.5*11.5*10^-6/7.649^2

=20391.608 N

F(net) = 42320 - 2*20391.608*7.5/7.649

= 2331.227 N
