The shown $H$ shaped apparatus contains an ideal incompressible liquid and has dimension as shown in figure . The diameters of the Tubes  are small as  compared to $h$ and $R$. The apparatus is rotated with a constant angular velocity $\omega$  about a symmetric vertical axis as shown in figure. The pressure at point $A$ is
  • A${P_0} + \rho gh$
  • B${P_0} + \rho gh + \frac{{\rho {R^2}\,{\omega ^2}}}{2}$
  • C${P_0} + \rho gh - \frac{{\rho {R^2}\,{\omega ^2}}}{2}$
  • D${P_0} - \rho gh - \frac{{\rho {R^2}\,{\omega ^2}}}{2}$

    An object with uniform density $\rho$ is attached to a spring that is known to stretch linearly with applied force as shown below.When the spring object system is immersed in a liquid of density $\rho_1$ as shown in the above figure, the spring stretches by an amount $x_1\left(\rho > \rho_1\right)$. When the experiment is repeated in a liquid of density $\left(\rho_2 < \rho_1\right)$, the spring stretches by an amount $x_2$. Neglecting any buoyant force on the spring, the density of the object is
