The escape velocity of a body on the earth's surface is `v_e`. A body is thrown up with a speed `sqrt5``v_e` , Assuming that the sun and planet do not influlence the motion of the body , velocity of the bidy at infinite distance , is

The escape velocity of a body on the Earth’s surface is v_e . A body is thrown up with a speed sqrt5 v_e . Assuming that the Sun and planets do not influence the motion of the body,the velocity of the body at infinite distance is v_oo .Then, the value of v_oo/v_e is

The escape velocity of a body from the earth's surface, v_("esc")= ……….. .
