Answer 1- The force on an electric field is determined by the amount of charge on the objects in the field. The force is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the charges. Mathematically, the force between two charges is given by Coulomb's law: F = k * q1 * q2 / r^2, where F is the force, k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.

Answer 2- As two charged objects move closer to each other, the force between them increases. This is because the distance between the charges decreases, leading to a stronger electric field between them. The force follows an inverse square law, meaning that as the distance between the charges decreases by a factor of 2, the force between them increases by a factor of 4.

Answer 3- To generate a current flowing through the wire, one can connect the ends of the wire to a voltage source, such as a battery. The voltage source creates an electric potential difference between the ends of the wire, causing the free electrons in the wire to move in response to the electric field. This movement of electrons constitutes an electric current flowing through the wire. Additionally, one can also induce a current in the wire by moving a magnet through the center of the cardboard tube, which creates a changing magnetic field that induces an electric current in the wire according to Faraday's law of electromagnetic induction.
