Steady two-dimensional heat conduction takes place in the body shown in the figure below. The normal temperature gradients over surfaces P and Q can be considered to be uniform. The temperature gradient $\frac{\partial T}{\partial X}$ at surface Q is equal to 10 K/m. Surfaces P and Q are maintained at constant temperatures as shown in the figure, while the remaining part of the boundary is insulated. The body has constant thermal conductivity of 0.1 W/m.K. The values of $\frac{\partial T}{\partial X}and\frac{\partial T}{\partial Y}$ at surface P are
