Introduction:
When two electrically charged particles with charges of different magnitudes are placed at a distance D from each other, they experience a force of attraction or repulsion based on the nature of their charges. However, if these two particles are put in contact and then placed at the same distance from each other, the nature of the new force between them will depend on the charges and their magnitudes.

Explanation:
1. Initial scenario:
- Let's consider two charged particles, A and B, with charges q1 and q2, respectively.
- Initially, if q1 and q2 have different magnitudes, they will experience a force of attraction or repulsion based on their charges. The magnitude of this force is given by Coulomb's Law: F = k * |q1 * q2| / D^2, where k is the electrostatic constant.

2. Putting the particles in contact:
- When particles A and B are put in contact, the charges redistribute due to the transfer of electrons between them.
- If q1 > q2, some electrons from particle A will transfer to particle B, resulting in particle A having a reduced charge (q1') and particle B having an increased charge (q2').
- The charge redistribution continues until both particles reach a state of equilibrium, where they have the same charge magnitude (q').

3. New scenario:
- Now, if particles A and B, with charges q' and q', respectively, are placed at the same distance D from each other, they will experience a new force.
- Since both particles have the same charge magnitude, they will either repel or attract each other based on the nature of their charges.
- If both particles have the same charge sign (positive or negative), they will repel each other. If they have opposite charge signs, they will attract each other.
- The magnitude of the new force can be calculated using Coulomb's Law again: F' = k * |q' * q'| / D^2.

Conclusion:
The nature of the new force between the two particles depends on the charge redistribution that occurs when they are put in contact. If the charges are redistributed such that both particles have the same charge magnitude, they will either repel or attract each other based on the nature of their charges. This new force can be calculated using Coulomb's Law.

New forces will repel each other
