V_0

α4πR^2(α\ll1)

The magnitude of electric field at the centre of the shell is reduced by $\frac{αV_0}{2R}$
The ratio of the potential at the centre of the shell to that of the point at $\frac{1}{2R}$ from centre towards the hole will be $\frac{1-α}{2-α}$
The magnitude of electric field at a point, located on a line passing through the hole and shell’s center, on a distance 2R from the center of the spherical shell will be reduced by $\frac{αV_0}{2R}$
The potential at the center of the shell is reduced by $2 a V_0$
