A region of space contains an electrostatic field represented by four concentric circular equipotential curves centered at the origin. Adjacent curves differ by a constant potential difference of \(\Delta V = 10\text{ V}\), with the potential decreasing outward from \(40\text{ V}\) to \(10\text{ V}\). Three points, labeled \(P\), \(Q\), and \(R\), are located in the regions between the curves. Which of the following correctly ranks the magnitude of the electric field \(E\) at points \(P\), \(Q\), and \(R\)?
