I couldn't understand why there is,
∂E[itex]_{y}[/itex] and ∂E[itex]_{z}[/itex] term in the equation,
for the x-component of the force on di-pole,
F[itex]_{x}[/itex] = q [ E[itex]_{x}[/itex] + ∂E[itex]_{x}[/itex]/∂x δx + ∂E[itex]_{y}[/itex]/∂y δy + ∂E[itex]_{z}[/itex]/∂z δz ] - qE[itex]_{x}[/itex]
Isn't both ∂E[itex]_{y}[/itex] and ∂E[itex]_{z}[/itex] term, should be zero along the x-component.
I understand, the net force on the di-pole, in an non-uniform electric field, should be,
F[itex]_{x}[/itex] = q [ E[itex]_{x}[/itex] + ∂E[itex]_{x}[/itex]/∂x δx] - qE[itex]_{x}[/itex]
Since the force on the ends of a di-pole are not the same in an non-uniform field. And therefore, there would be a net force on the di-pole.
