The image above represents the escape velocity.

To compute the escape velocity of a field, two essential parameters are needed and the parameters are acceleration due to gravity (g) and radius (r).

The formula for calculating the escape velocity:

V = √(2gR)

Where;

V = Escape velocity

g = Acceleration due to gravity

R = Radius

Let’s solve an example;

Find the escape velocity of a field when the acceleration due to gravity is 12 and the radius is 24 cm.

This implies that;

g = Acceleration due to gravity = 12

r = Radius = 24 cm

V = √(2gR)

V = √(2 x 12 x 24)

V = √(576)

V = 24

Therefore, the **escape velocity** is **24 m/s.**
