The Total solution for NCERT class 6-12
a)┬аNo
(b)┬аNo
(c)┬аNo
(d)┬аYes
Escape velocity of a bodyfrom the Earth is given by the relation:
g = Acceleration due togravity
R┬а= Radius of the Earth
Itis clear from equation (i) that escape velocity┬аvesc┬аis independent of the massof the body and the direction of its projection. However, it depends ongravitational potential at the point from where the body is launched. Sincethis potential marginally depends on the height of the point, escape velocityalso marginally depends on these factors.
