An artifical satellitee of mass `100 kg` is in a circular orbit at `500 km` above the Earth's surface. Take redius of Earth as `6.5 xx 10^(6) m`.(a) Find the acceleration due to gravity at any point along the satellite path (b) What is the centripetal acceleration o fthe satellite?

Explanation

`g' = g((R)/(R + h))^(2)`, Centripetal acceleration,
`a = (upsilon^(2))/((R + h)) = (gR^(2)//(R + h))/(R + h) = (gR^(2))/((R + h)^(2)) = g'`
