Force Balance | MCQs

Explanation

Explanation

A body in equilibrium means all the forces acting on it are balanced, resulting in no net force.

Since acceleration is directly related to the net force (F = ma), if the net force is zero, then the acceleration must also be zero. 

Explanation

A moving object is in equilibrium if it moves with a constant velocity; then its acceleration is zero.

A zero acceleration is the fundamental characteristic of an object in equilibrium.

Explanation

A body is in translational equilibrium when the vector sum of all forces acting on it is zero, meaning ∑F = 0.

This implies the sum of forces in both the x and y directions are also zero, i.e., ∑Fx = 0 and ∑Fy = 0.

The statement ∑τ = 0 is related to rotational equilibrium, not translational equilibrium.

The condition ∑β = 0 is not standard terminology in physics.
