Question

An artificial satellite is moving in a circular orbit of radius 42000 km. Calculate it's velocity of takes 24 hours to revolve round the earth? Please step by step explain Karo koi.​

Answer 1

$\underline\bold\blue{Question} = >$

A satellite is moving in circular orbit of radius 42250 km. Calculate its speed if it takes 24 hour to revolve around the earth.

$\underline\bold\blue{Given} = >$

Radius of the orbit =>42000 km

Time taken to complete one revolution around the earth=>24 hours

$\underline\bold\blue{To \: find} = >$

Speed if it takes 24 hours to revolve round the earth

$\underline\bold\blue{Answer} = >$

Radius of the circular orbit of along which the satellite is moving=>42250 km

Time taken by the satellite to complete one revolution around the earth=>24 hours

$\bold{We \: know \: speed \: } = \frac{Total \: distance}{Time \: taken}$

Distance travelled by the satellite in one revolution around Earth=2×π×r

Note:-

r=radius

π=22/7

Total distance travelled

=2×π×42250

=2×22/7×42250

=265571.43

Total time taken=24h

$\bold{Therefore \: speed} = \: \frac{265571.43}{24}$

=11065.47km/hr

The speed of the satellite=11065.47km/hr
