If the sum of all the forces acting on a body is zero, it may be concluded that the body

AMust be in equilibrium

BMay be in equilibrium

CMay be in equilibrium provided that forces are concurrent

DMay be in equilibrium provided that forces are parallel

Answer:

C. May be in equilibrium provided that forces are concurrent

Read Explanation:

If the sum of all forces acting on a body is zero, it does not ensure that the body is in equilibrium. For instance, two equal and opposite forces acting at a distance apart cause rotation and not translational motion. However, if the forces are concurrent, the torque produced is zero, and the body is both translationally and rotationally stable.
