SUMMARY
Coulomb's law defines the electrical force between two charges, which can be calculated using the formula F = k * |q1 * q2| / r², where k is Coulomb's constant. When two conducting spheres with charges q1 = -2 nC and q2 = 6 nC are brought into contact, they share their charges equally, resulting in both spheres having a charge of 2 nC after separation. The magnitude of the electrical force between the spheres, now both positively charged, can be calculated using their new charges and the distance of 3.00 cm, resulting in a repulsive force.
