Chapter 7, Problem 15Q

(a)

To determine

The escape speed from the surface of the Sun if the mass of the Sun is $1.989\times {10}^{30}\text{ kg}$ and its radius is $\text{6}\text{.96}\times {\text{10}}^{\text{8}}\text{ m}$.

(b)

To determine

The reason for very less escape of hydrogen gas from the Sun’s atmosphere if the mass of the Sun is $1.989\times {10}^{30}\text{ kg}$ and its radius is $\text{6}\text{.96}\times {\text{10}}^{\text{8}}\text{ m}$.
