The edge dislocation sketched below is in a cubic solid with a shear modulus of $100$ GPa and a Poisson's ratio of $0\mathrm{.}5.$ The magnitude of its burgers vector is $0\mathrm{.}2$ nm and is in the $+y$ direction. It has a tangent vector in the $+z$ direction.$|$

A stress of ${}_{xy}=50$MPa is applied to the solid. Calculate the magnitude $($in units of $\frac{N}{m})$ and direction of the force per unit length acting on the dislocation.

Answer formatted as magnitude $(\frac{N}{m})$: direction.

$1E-2$:$+j$

$1E-2$:$+i$

$1E-2$:$k$

$0$
