What is the magnitude and direction of the gravitational force that acts on a person who weighs 500 N at Earth's surface?
 
  What will be an ideal response?

Question 2

Ekapluto is an unknown planet that has two spherical moons in circular orbits. The table summarizes the hypothetical data about the moons. Both moons have low axial spin rates.
 
  (G = 6.67  10-11 N  m2/kg2)
 
   Mass Radius Orbital radius Orbital period
  Moon A 4.0  1020 kg 2.0  108 m 4.0  106 s
  Moon B 1.5  1020 kg 2.0  105 m 3.0  108 m
 
  The acceleration due to gravity at the surface of Moon B is
  A) 0.10 m/s2.
  B) 0.15 m/s2.
  C) 0.20 m/s2.
  D) 0.25 m/s2.
  E) 0.30 m/s2.
