MCQ
If two liquids of same masses but densities $\rho_1$ and $\rho_2,$ respectively are mixed, then density of mixture is given by:
- A$\rho=\frac{\rho_1+\rho_2}{2}$
- B$\rho=\frac{\rho_1+\rho_2}{2\rho_1+\rho_2}$
- ✓$\rho=\frac{2\rho_1\rho_2}{\rho_1+\rho_2}$
- D$\rho=\frac{\rho_1\rho_2}{\rho_1+\rho_2}$
