Correct Answer - C
`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.
