The molecule with symmetrical & linear geometries have zero dipole moment because they are vector in nature & the dipole of different bonds cancel with one another & in a unsymmetrical molecule & bent geometries, the geometries have specific dipole moment because the bond polarities do not cancel each other.
Since there is no lone pair at the central atom (Be) and there are two bond pairs, BeH2 is of the type AB2. It has a linear structure.
Dipole moments of each H–Be bond are equal and are in opposite directions. Therefore, they nullify each other. Hence, BeH2 molecule has zero dipole moment.
While in Be---H , dipole moment of Be & H are not equal & they donot nullify each other.hence has a specific dipole moment.

Hello friend...!!
The net dipole moment of BeF2 molecule is zero because, the hybridisation of BeF2 molecule is sp.
Thus it is linear shape. The F atom that is more electronegative attracts the electron Clould of Be in equal and opposite direction this cancel out the effect of each other since they are equal and opposite.
So the net dipole Φ = 0 for BeF2.
Hope it is useful...!!
