Answer:
0 J
Explanation:
[tex]W[/tex] = Work done on the satellite in circular orbit about earth by earth
[tex]F[/tex] = Force on gravity on satellite by earth
[tex]d[/tex] = displacement of the satellite
[tex]\theta[/tex] = Angle between the force on gravity and displacement = 90
We know that, Work done is given as
[tex]W = F d Cos\theta\\W = F d Cos90\\W = F d (0)\\W = 0 J[/tex]
