- Calculate the magnitude and direction of coulomb force on the last charge. 91 = 6µC 92 = 1.5µC 93 = -2µC Зст 2ст The magnitude is The direction is Determine the magnitude of force on the first charge.Because of their net negative charge, bacteria are easily attracted to and adhere to surfaces on which they can proliferate, forming bacterial biofilms, thin films of bacteria coating the surface. Bacterial biofilms are especially problematic on indwelling medical devices (IMDS), which are devices inserted into a patient and include catheters, heart valves, and artificial joints. Contaminated IMDS are the most common source of infection in humans. A number of mitigation methods are in use today, including antibacterial graphene oxide coatings and the use of electric fields and surface charges to repel bacteria. In a hospital operating room, due to an unexpected complication in the surgical procedure, and in violation of protocol, a catheter that was removed from its sterile pouch before the complication is being used hours after being exposed to the air in the room.
