An artificial satellite is moving in a circular orbit of radius 42250Km. Calculate its speed if it takes 24 hours to revolve around the earth.

Text Solution

Verified by Experts

Radius = 42250 km
`=42250xx1000M`
Time required = 24 hours
`=24xx3600` sec
Speed = ?
Speed = `("distance")/("time")=(2pir)/("time")`
`=2xx(22)/7xx(42250xx1000)/(24xx3600)`
Speed = 3073.74 m/s
