Does the escape speed of a body from the earth depend on
(i) mass of the body
(ii) the location from where it is projected
(iii) the direction of projection
(iv) the height of the location from where the body is launched?
(i) No, escape velocity is independent of the mass of the
body.
(ii) Yes, escape velocity depends (through slightly on the location from where the body is projected because with location g changes and so should change.
(iii) No, escape velocity is independent of the direction of projection.
(iv) Yes, escape velocity depends (through slightly) on the height of location from where the body is projected as g depends on height.
