Question

a satellite is revolving round earth with speed V in an Orbit of radius R if r is decreased by 1 percent the speed of the satellite will:

Answer 1

Answer:

the speed of the satellite will increase

Answer 2

SOLUTION

Orbital speed v ⁰ =

$\sqrt{ \frac{gm}{r} }$

because,,

$\: g \: m \: are \: constan t \: v0 \: = k \: \frac{1}{ \sqrt{r} } \\ by \: power \: law \: of \: error \: triangle \: \frac{v0}{v0} \\ = \frac{1}{2} \frac{r}{r}$

or % change in v ⁰ = 1/2 % change in r

because,,

percentage increase in

$v0 = \frac{1}{2} \times (1) \\ = 0.5\%$
