On a planet, a gravitational force F acts on a mass of 6.0 kg. The mass is moved by force F a distance of 30 m in the direction of the gravitational field. The work done by the field is 450 J. What is the force F on the mass and what is the acceleration of free fall g on the planet?

1. AF = 0.067 N, g = 0.011 m s⁻²
2. BF = 0.067 N, g = 0.40 m s⁻²
3. CF = 15 N, g = 2.5 m s⁻²
4. DF = 15 N, g = 90 m s⁻²
