If the gain of the critically damped system is increased, it will behave as follows:

1. Determine the initial behavior: A critically damped system initially exhibits a response that quickly reaches its steady-state without any oscillations.

2. Increase the gain: By increasing the gain of the system, the response will become more sensitive to changes in the input signal.

3. Analyze the effect: As the gain is increased, the system may transition from being critically damped to becoming overdamped or underdamped.

4. Underdamped behavior: If the gain is increased beyond the critical damping threshold, the system may start exhibiting oscillations or overshoot in its response. This behavior is characteristic of an underdamped system.

5. Oscillatory behavior: If the gain is further increased, the system may exhibit more pronounced oscillations in its response. This behavior is typical of an oscillatory system.

6. Critically damped behavior: If the gain remains within the range that maintains critical damping, the system will continue to exhibit a response that quickly reaches its steady-state without any oscillations.

7. Overdamped behavior: If the gain is increased significantly beyond the critical damping threshold, the system may exhibit a slower response without any oscillations. This behavior is characteristic of an overdamped system.

Therefore, if the gain of the critically damped system is increased, it can behave as underdamped, oscillatory, critically damped, or overdamped, depending on the extent of the gain increase.
