The mass of the Mars exploration rover is 1,063 kg. The gravity on Mars is about 0.38 that of Earth.1)Where would the normal force exerted on the rover when it rests on the surface of the planet be greater?

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

2. they have negligible mass.
