Derive an equation for escape velocity and calculate the escape velocity of our Sun.

$$F= G \cdot \dfrac{m_1 \times m_2}{x^2}$$, where $$F$$ is the gravitational force experienced by two bodies with masses $$m_1$$ and $$m_2$$ and $$x$$ is the distance between them.

Details and Assumptions:

• $$G = 6.67408 \times 10^{-11} \text{ m}^3 \text{ kg}^{-1} \text{ s}^{-2}$$.

• Mass of the sun is $$2\times10^{30} \text{ kg}$$.

• Radius of the sun is $$696.3 \times10^6 \text{ m}$$.
