A single crystal chromium specimen contains a mobile edge dislocation density

A single crystal chromium specimen contains a mobile edge dislocation density of 8^10 m^-2. If a load is applied to the a specimen in the [212] direction relative to the crystal, what is the Burgers vector of the edge dislocation that will slip first when the critical resolved shear stress is exceeded (give the direction of the vector) urgent please
