A prismatic cantilever prestressed concrete beam of span length, $L = 1.5 \text{ m}$ has one straight tendon placed in the cross-section as shown in the following figure (not to scale). The total prestressing force of $50 \text{ kN}$ in the tendon is applied at $d_{c}=50\text{ mm}$ from the top in the cross-section of width, $b= 200 \text{ mm}$ and depth, $d=300 \text{ mm}$.

If the concentrated load, $\text{P=5 kN}$, the resultant stress (in $\text{Mpa}, \textit{in integer}$) experienced at point ‘$Q$’ will be _____________
