According to Newton's Second Law of Motion, the relationship between the force applied to an object and the object's acceleration is defined by the equation F = ma, where F represents the force applied, m is the mass of the object, and a is the acceleration produced. When an external force acts on a body that is moving with uniform speed, that force can cause a change in its motion. Specifically, the change in motion (acceleration) is directly proportional to the magnitude of the applied force. This means that if a greater force is applied, the acceleration will also increase proportionally, reflecting the law's core principle.

If there is no net external force acting on the body, it will continue to move at its uniform speed. However, when an external force is applied, the body will experience a change in its velocity, leading to acceleration. This is because the law emphasizes that the effect of the external force will be felt immediately, causing a change based on the strength of that force relative to the object's mass.

The other options do not accurately reflect this principle. A body maintaining uniform speed without an external force does not change, whereas the options suggesting that the body either stops suddenly or experiences a constant-rate acceleration do not align with the correct interpretation
