Question

if velocity given to an object from the surface of the earth is n times the escapes velocity then what will be the residual velocity at inifinity​

Answer 1

Answer:

Let residual velocity be v then from energy conservation 12m(nve)2−GMmR=12mv2+0

⇒v2=n2v2e−2GMR=n2v2e−v2e−v2e=(n2−1)v2e⇒v=(n2−1−−−−−√)ve
