A body will be in translational equilibrium if the vector sum of all the forces acting on it is:
Correct answer: A. 0
- A. 0
- B. Min
- C. Max
- D. Equal
Explanation
A body is said to be in equilibrium if all the sum of all forces acting on it become equal to zero. It means an object is in translational equilibrium when overall acceleration is zero. Therefore, it is either not moving or moving at a constant velocity.

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
