WebApr 11, 2024 · The gravity part of the field equations is not affected by the electromagnetic Chern–Simons term and it only provides an effective potential to the equation of motion for the scalar field. When we pick the coupling constant, electric charge, and magnetic charge appropriately, the dyonic RN black hole will become unstable and there will exist ... WebFigure 5.34 The net electric field is the vector sum of the field of the dipole plus the external field. Recall that we found the electric field of a dipole in Equation 5.7. If we rewrite it in terms of the dipole moment we get: E → ( z) = –1 4 π ε 0 p → z 3. The form of this field is shown in Figure 5.34. the hyperpycnite problem
