g=GM/r^2
g on venus is 0.80w as radius is kept constant
m of object is kept constant
w α g
w(venus( is 0.8w
during satellite motion we know that total energy is always conserved
so here we will have

here we know that


now at other position

now from above equation we have

now we have


so its kinetic energy will be 3500 MJ
