# Explanation:
## Step1: Recall Coulomb's Law for ionic bonds
The strength of an ionic bond is related to the formula $F = k\frac{q_1q_2}{r^2}$, where $q_1$ and $q_2$ are the ionic charges and $r$ is the distance between ions. A stronger bond corresponds to a larger force $F$.
For $NaCl$, the charges are $q_{Na^+}= + 1$, $q_{Cl^-}=-1$. For $BeO$, the charges are $q_{Be^{2+}}=+2$, $q_{O^{2 -}}=-2$. The distance between ions: $Be^{2+}$ is smaller than $Na^+$ ($r_{Be^{2+}}<r_{Na^+}$), $O^{2 -}$ is smaller than $Cl^-$ ($r_{O^{2 -}}<r_{Cl^-}$), so $r_{BeO}<r_{NaCl}$.
## Step2: Analyze the effect of charge and distance on bond strength
Using $F = k\frac{q_1q_2}{r^2}$, for $BeO$, $q_1q_2=(+2)\times(-2)= - 4$, and for $NaCl$, $q_1q_2=(+1)\times(-1)=-1$. Also, $r_{BeO}<r_{NaCl}$.
Since $BeO$ has larger ionic charges ($\vert q_1q_2\vert$ is larger for $BeO$) and a smaller distance ($r$) between ions compared to $NaCl$, $BeO$ has a stronger ionic bond.

# Answer:
BeO will have a stronger bond because it has a larger ionic charge, and a smaller distance between ions.
