A dipole consisting of charges +-e 220mm apart, is placed among two very large (essentially infinite) sheets carrying equal however opposite charge densities of 125 m uC/m^2
1) What is the maximum potential energy this dipole can have due to the sheets?
2) What is the maximum torque the sheets can exert on the dipole?
How should it be oriented relative to the sheets to attain this value?
3) What net F do the two sheets exert on the dipole?
