What type of force would two objects have with both positive and negative charge with a distance of 10mm?

Two objects with both positive and negative charges will exert an electrostatic force on each other. The force experienced by the objects will depend on the magnitude of their charges, the distance between them, and the medium in which they are located. The force between them can be calculated using Coulomb's law, which 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.

Mathematically, the force (F) between two charges (q1 and q2) separated by a distance (r) in a vacuum is given by:

F = k(q1 * q2) / r^2

Where k is the Coulomb's constant.

So, the force between two objects with both positive and negative charge with a distance of 10 mm can be calculated using this formula.
