Final answer:

The electrostatic force between two charged objects can be calculated using Coulomb's law which is A)
9.76 x 10^-11 N

Step-by-step explanation:

The electrostatic force between two charged objects can be calculated using Coulomb's law:


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

Where F is the electrostatic force, k is the electrostatic constant
(9 x 10^9 Nm^2/C^2), q1 and q2 are the charges of the objects, and r is the distance between them.

Plugging in the values from the question, we get:

F =
(9 x 10^9 Nm^2/C^2) * ((-2.3 x 10^-6 C) * (-4.2 x 10^-6 C)) / (0.099 m)^2

= 9.76 x 10^-11 N

So the correct answer is A)
9.76 x 10^-11 N.
