Hemisphere E-Field (Qualitative)

A hollow hemispherical shell of radius $R$ with uniform area charge density has the center of its base at the origin in the $xyz$ coordinate system. Its base is parallel to the $xy$ plane.

In Case 1, there is a test point at $(x,y,z) = (0,0,0)$ . In Case 2, there is a test point at $(x,y,z) = (\frac{3}{4} R,0,0)$ .

Let $E_1$ be the magnitude of the electric field at the test point in Case 1. Let $E_2$ be the magnitude of the electric field at the test point in Case 2.

Consider the following ratio:

$\alpha = \frac{E_2}{E_1}$

Which statement is true about $\alpha$ ?
