Solve the all parts of given question:
Question: Two small conducting spheres are separated by a distance of 25.0 cm. One carries a charge of 30.0 µC while the other carries a charge of +45.0 µC.
Part A: What is the magnitude of the force experienced by one sphere due to the other?
Part B: If the spheres are brought into contact and then separated to a distance of 25.0 cm, what will be the magnitude of the force experienced by one sphere due to the other?
Part C: Is the force attractive or repulsive?
