According to Coulomb's law, the electrostatic force (F) between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Let's assume the original charges are q1 and q2, and the force between them is F. If both charges are doubled (2q1 and 2q2), the force between them can be calculated.
Using Coulomb's law:
F_new = k * (2q1) * (2q2) / r^2
= (4 * k * q1 * q2) / r^2
= 4 * (k * q1 * q2) / r^2
= 4F
Therefore, the force between the charges will be 4F when both charges are doubled.
Electrostatic force F exists between two point charges. If the both charges are doubled, the force between the charges will be
F
4 F
2 F
F/4
