Question

A $$10$$ kg satellite completes one revolution around the earth at a height of $$100$$ km in $$108$$ minutes. The work done by the gravitational force of earth will be?

A
108×100×10J
B
108×10100J
C
0J
D
100×10108J

Solution

The correct option is C $$0$$JListing out the FormulaWork Done = Force x DisplacementForce = Mass x AccelerationConsidering the displacement of this SatteliteOne complete circle = Displacement = 0∴ Work Done by Gravity is ZeroPhysics
