Final answer:
The resultant force after removing the 3N force from a system of 2N, 3N, and 4N forces acting on a point in equilibrium is 0N.
Step-by-step explanation:
When 2N, 3N, and 4N forces are acting on a point in equilibrium, the resultant force is equal to zero. This means that the forces cancel each other out and there is no net force acting on the point. So, after removing the 3N force, the resultant force will still be zero (0N).
