Does the escape speed of a body from the earth depend on (a) the mass of the body. (b) the location from where it is projected. © the direction of projection, (d) the height of the location from where the body is launched?

Explanation

To determine whether the escape speed of a body from the Earth depends on various factors, we can analyze each part of the question systematically.

### Step-by-Step Solution:

1. **Understanding Escape Speed**:
The escape speed (vₑ) is the minimum speed required for an object to break free from the gravitational attraction of a celestial body without any additional propulsion. The formula for escape speed is given by:
\[
vₑ = \sqrt{2gR}
