# Electric force on the interface between two dielectrics

Suppose two electrodes maintained at a voltage difference of $$V_0$$ are separated by a distance of $$d=d_1+d_2$$. Between the electrodes are two different dielectric medium of $$\epsilon_1$$ and $$\epsilon_2$$, each with thickness $$d_1$$ and $$d_2$$. We can solve for the electric fields in the dielectric regions to get $$E_1=\frac{\epsilon_2 V_0}{\epsilon_1 d_2+\epsilon_2 d_1}$$ and $$E_2=\frac{\epsilon_1 V_0}{\epsilon_1 d_2+\epsilon_2 d_1}$$. Is there an electric force acting on the interface between the two dielectrics? I'm asking as there is a difference in the Maxwell's stress tensor, but then I'm not too sure how to interpret it (like explain it by just considering the charges/bound charges).
