An artifical satellite cicles round the earth at a distance of 3400 km. Calculate the orbital velocity. Given the radius of the earth is 6400km. G` = 9.8 ms^(-2)`.

Text Solution

Verified by Experts

Given, radius of earth, R = 6400 km
Distance of satellite from earth, h = 3400 km
`:.` Orbital velocity of an artifical satellite can be given as
`v_(o)=Rsqrt((g)/(R+h))=64xx10^(5)sqrt((9.8)/((64+34)xx10^(5)))`
`rArr v_(e)=6400 "ms"^(-1)`.
