MCQ
When a body is in translatory equilibrium:
  • A
    The body is definitely at rest
  • B
    The body is definitely in the state of uniform motion
  • C
    The body will be either at rest or in the state of uniform motion
  • D
    None of these
✓

Answer

  1. The body will be either at rest or in the state of uniform motion

Explanation:

When a body or a system is in equilibrium, there is no net tendency to change.

Similarly when no force is acting to make a body move in a line, the body is in translational equilibrium; when no force is acting to make the body turn, the body is in rotational equilibrium.
