A two-dimensional electrostatic potential in the first quadrant of the \(xy\)-plane is represented by four equipotential contours labeled \(40\text{ V}\), \(30\text{ V}\), \(20\text{ V}\), and \(10\text{ V}\). Along the positive \(x\)-axis, the contours are perpendicular to the \(x\)-axis with a uniform spacing of \(1.0\text{ cm}\), decreasing in potential in the \(+x\)-direction, and point \(P\) lies on the \(20\text{ V}\) contour on this axis. Along the positive \(y\)-axis, the contours are perpendicular to the \(y\)-axis with a uniform spacing of \(2.0\text{ cm}\), decreasing in potential in the \(+y\)-direction, and point \(Q\) lies on the \(20\text{ V}\) contour on this axis. Which of the following diagrams best represents the direction and relative magnitude of the electric field vectors, \(\vec{E}_P\) and \(\vec{E}_Q\), at points \(P\) and \(Q\)?
