The kinetic energy needed to project a body from earth's surface to infinity is known as its escape energy.
KE = (GMem)/R which is equal to mgR since gR=(Gme)/R
make it brialent answer
dushra answer MIL jaane do
okh
i need only on brialeant so make it ...
okay I will make
okh
Vishal yaar please talk to her
u are ignoring her
if not then talk to her in the inbox

Answer to your question is
The escape velocity is vg=√2gR
Kinetic energy=1/2*m*vg^2
=1/2*m*2gR
=mgR
never
yrr why he thinking like that
JUST
stay away
u said me brother na then also.......
who i ??
no..... yash
just stay away from me yash
And u all know whom i love the most....
is my physics book
