Physics

The object D is in equilibrium.

Since the forces are equal in magnitude, opposite in direction, and act along the same line, they cancel each other out entirely. There is no net force or torque acting on the object, so it remains stationary or moves at constant velocity. Therefore, the object is in equilibrium.

 

Option A

In this case, the forces are equal in magnitude, but since they not acting along the same line do not cancel each other out completely, it will cause rotation but not linear equilibrium.
