An object is at rest on the ground. The object experiences a downward gravitational force from Earth.

An object is at rest on the ground. The object experiences a downward gravitational force from Earth. Which of the following predictions is correct about why the object does not accelerate downward? Select two answers. Justify your selections.A) The bonded molecules of the object are repelled upward by the bonded molecules of the ground with the same magnitude as the gravitational force downward on the object.B)The normal force is exerted upward on the object from the ground with the same...

5a) The gravitational force on a particle of mass m inside the earth at a distance r from the center (r < RE the radius of the Earth) is F = −mgr/R. Show that in an evacuated, frictionless tube, the particle would move back and forth through the tube with a simple harmonic motion and find the period of that motion.
