Answer

$BeCl_2$ does not have a net dipole moment.

Work Step by Step

The bonds between Be and Cl are polar. However, $BeCl_2$ has a linear electron geometry, so the partial charges from the two polar bonds between the Be and each of the Cl atoms cancel each other out. Thus, there is no net dipole moment.
