Answer

a) False b) No

Work Step by Step

a) When an object is at rest, it will still have the force of gravity and normal force, just they are balanced so the object doesn't move. b) Based on Newton's first law, if all forces balance, the object can still move, just at constant velocity where acceleration is 0, so no, if the net force is zero the object doesn't have to be at rest.
