which object is in static equilibrium?\n a rolling ball that has a net force acting on it\n a cruising car that has no net force acting on it\n a book that has no net force acting on it and is sitting on a table\n a vase that has a net force acting on it and is sitting on a shelf

which object is in static equilibrium?\n a rolling ball that has a net force acting on it\n a cruising car that has no net force acting on it\n a book that has no net force acting on it and is sitting on a table\n a vase that has a net force acting on it and is sitting on a shelf

Answer

Answer:

C. a book that has no net force acting on it and is sitting on a table

Explanation:

Step1: Define static equilibrium

Static equilibrium means an object is at rest and the net - force acting on it is zero.

Step2: Analyze each option

  • A rolling ball with a net force is not in equilibrium as it is moving and has a non - zero net force.
  • A cruising car is in motion (dynamic), not static equilibrium although net force is zero.
  • A book sitting on a table with no net force is at rest and satisfies static equilibrium conditions.
  • A vase with a net force acting on it is not in equilibrium.
