A particle is located 1,800 km above the surface of earth. Calculate the escape velocity of the particle. Take Radius of earth = 6,400 km
`g = 9.8 m//s^(2)`

Explanation

To calculate the escape velocity of a particle located 1,800 km above the surface of the Earth, we can follow these steps:

### Step 1: Understand the formula for escape velocity
The escape velocity \( v \) from a height \( h \) above the surface of the Earth is given by the formula:
\[ v = \sqrt{2g \left( \frac{R}{R + h} \right)} \]
where:
