For a body to be in complete equilibrium:

Correct answer: D. Linear acceleration and angular acceleration both should be zero

  • A. Linear acceleration is zero
  • B. Angular acceleration is zero
  • C. Linear acceleration is zero but angular acceleration is not zero
  • D. Linear acceleration and angular acceleration both should be zero

Explanation

For a body to be in complete equilibrium, it must not experience any net force or torque. This means that both its linear acceleration and angular acceleration should be zero (Option D). This ensures that the body is neither translating nor rotating. Option A and B only address one aspect of motion each, and Option C allows for rotational motion, which contradicts the state of complete equilibrium.

About Newton's Laws of Motion

Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
