If $\mathrm{\alpha },\mathrm{\beta },\mathrm{\gamma }$ are real roots of the equation ${\mathrm{x}}^3-3{\mathrm{px}}^2+3\mathrm{qx}-1=0$ . Then the centroid of the
triangle whose vertices are$\left(\mathrm{\alpha },\frac{1}{\mathrm{\alpha }}\right),\left(\mathrm{\beta }, \frac{1}{\mathrm{\beta }}\right) \mathrm{and} \left(\mathrm{\gamma }, \frac{1}{\mathrm{\gamma }}\right)$ is...
