Question

the speed of near satellite is V it's orbital Velocity ,when it's altitude is increased by half of earth's radius, is​

Answer 1

Answer:

Orbital velocity of artifical satellite near eart surface is given by , v=

R

GM

...1

And orbital velocity at a distance r, is given by v

′

=

r

GM

so for r−R/2, orbital velocity is v

′

=

R

2GM

....2

Taking ratio of eq1 and eq 2 we get ,

v

v

′

=

2

this gives , v

′

=

2

v
