The escape speed of a body from the earth depends upon

Options

A. the mass of the body
B. the direction of projection
C. the latitude and altitude of the location, from where the body is launched
D. none of the above

Answer

C

Explanation

`v_(e)=sqrt((2GM)/(R ))`
It is independent of the mass of the body and the direction of projection. It depends upon the gravitational potential (V) at the point of projection. `V=-(GM)/(r )` and it depends upon the latitude and altitude (height of the point). Thus `v_(e)` depends upon latitude and altitude.
