हिन्दीThe inner core of the Sun has a temperature exceeding \( 10^7\text{ K} \) and its outer surface has a temperature of about \( 6000\text{ K} \). Given the mass of the Sun \( = 2.0 \times 10^{30}\text{ kg} \) and radius of the Sun \( = 7.0 \times 10^8\text{ m} \), the mass density of the Sun is expected to be in the range of:
Correct answer · Option 1
Densities of solids and liquids
Explanation
Density \( \rho = \frac{M}{V} = \frac{2.0 \times 10^{30}}{\frac{4}{3}\pi (7.0 \times 10^8)^3} \approx 1400\text{ kg m}^{-3} \), which falls in the range of densities of solids and liquids.
