This is not a homework question I encountered this while revisiting the Electric Dipoles . First of all if someone explains me why the dipole So in the image above which way should the dipole rotate ? Anti Clock Wise or Clock Wise . What My intuition says is the Energy of a dipole is U = -p.E Which is -pEcosθ So the Energy Graph would be So theres a Stable Equilibrium at 0 and unstable equilibrium at ∏ So what I know is that angle is angle made between the E field and the Dipole moment . What I am not getting is which way is the angle measured ? So if I rotate the dipole moment all the way to bottom will the angle still be same ? Like in the figure ? Also still which way the dipole rotate it seems easier for it rotate counter clockwise . But Will it ?
