The three - dimensional state of stress at a point is given by: $$\left[ \sigma \right] = \left[ {\matrix{ {30} & {10} & { - 10} \cr {10} & 0 & {20} \cr { - 10} & {20} & 0 \cr } } \right]MN/{m^2}$$\$

The shear stress in the $$x-y$$ plane at the same point is then equal to

A
zero MN/m2
B
$$-10$$ MN/m2
C
$$10$$ MN/m2
D
$$20$$ MN/m2
