Like charges repel and unlike charges attract. Coulomb’s law states that the force F of attraction or repulsion between two charges, q1 and q2 is given by F= kq1q2/f^2, where k is constant and r is the distance between the positive charges. Suppose you were to graph F as a function of r for two positive charges

Step-by-step explanation:

The electrical force between two unlike charge is given by :

k is electrostatic constant

q₁ and q₂ are two charges

r is the distance between charges

It is clear that the electric force is inversely proportional to the square of the distance between them.

The graph F as a function of r for two positive charges is shown in the attached figure. It is a hyperbola.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
