Assume that the efficiency of the drone's magnetic induction charging system is directly proportional to the operating frequency ($f$) and inversely proportional to the square root of the distance ($d$) between the drone's gripper and the power line, represented as $Efficiency = k * (f / \sqrt{d})$, where $k$ is a constant. If the drone initially operates at a frequency of 60 kHz and a distance of 4 cm, and then adjusts to a frequency of 120 kHz and a distance of 1 cm to optimize charging, by what factor does the charging efficiency change?

Study Notes
- Drones have evolved significantly since the first model in 1907.
- Modern quadcopters can fly at high altitudes and handle various tasks.
- Limited battery life often restricts modern quadcopters' capabilities.
- Professor Emad Ebeid and his team at the University of Southern Denmark created a technology that allows drones to recharge from overhead power lines.
- An internal computer uses radar sensors and cameras to locate the nearest power line when the drone's battery is low.
- The drone attaches itself to the power line using a specially designed gripper.
- A magnetic circuit activates upon connection, enabling the drone to draw power from the line, similarly to wireless phone chargers.
- The drone was revealed in March 2024 at the IEEE International Conference on Robotics and Automation.
- A 9.5-pound (4.3 kg) prototype successfully recharged itself five times and stayed airborne for over two hours during testing.
- Professor Ebeid envisions these drones revolutionizing industries, particularly power line inspections and maintenance.
- Using drones for power line work can improve efficiency, reduce costs, and enhance safety compared to using helicopters and ground crews.
