Question

An object weighing 100 kg is dropped front the tenth floor of a building. Which of the following correctly expresses the gravitational force that is pulling the object toward the center of the Earth?

Answer 1

For this case, the gravitational force is given by:
 F = m * g
 Where,
 m: mass of the object
 g: acceleration due to gravity
 Substituting values we have:
 F = (100) * (9.8)
 F = 980 N
 Answer:
 The gravitational force that is pulling the object to the center of the Earth is:
 F = 980 N
