A. 4.0 m/s2
B. 6.0 m/s2
C. 8.0 m/s2
D. 10 m/s2
E. 12 m/s2

Pretend an object is set sliding on a huge frictionless plane in contact with the surface of Earth as shown. Once the object is set in motion it will
1) theoretically slide to the right forever 2) slide back and forth 3) slow down and stop because 4) of its inertia. 5) gravitational force decreases with increasing distance. 6) the object is sliding "uphill" and then "downhill" relative to the round Earth.
