Answer:
0 J
Step-by-step explanation:
= Work done on the satellite in circular orbit about earth by earth
= Force on gravity on satellite by earth
= displacement of the satellite
= Angle between the force on gravity and displacement = 90
We know that, Work done is given as
![W = F d Cos\theta\\W = F d Cos90\\W = F d (0)\\W = 0 J](https://img.qammunity.org/2020/formulas/physics/high-school/63jy4n23yas14e25e1rzqjkxxsxko217k7.png)
