First analyze the force that is acting on each charge. The force is determined by the two. objects interacting. If you start with Case 1, the charges are q and 4 q with a separation of d. That means. the force is 4kqq/d2 .
DNA is the most powerful tool available for identification in forensic investigations. Because of its ability to link physical evidence found at a crime scene to a single person, it is often referred to as a âdigital fingerprint.â This method is so precise that it can ensure pinpoint accuracy, down to one in a billion.
DNA profiling (also called DNA fingerprinting, DNA testing, or DNA typing) is a forensic technique used to identify individuals by characteristics of their DNA. In 1992, DNA from a palo verde tree was used to convict Mark Alan Bogan of murder. 2  DNA from seed pods of a tree at the crime scene was found to match that of seed pods found in Bogan's truck. 3  This is the first instance of plant DNA admitted in a criminal case.
