The electrical force acting on an alpha particle with a charge of +2.0e, when it is 2.0 x 10-14 m away from a gold nucleus with a charge of +79e, is calculated to be 91 N using Coulomb's Law. This law states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The formula used is F = k * (|q1 * q2|) / r2, where k is Coulomb's constant.
PREREQUISITESStudents in physics, particularly those studying electromagnetism, as well as educators looking to clarify concepts related to electric forces and Coulomb's Law.
