Final answer:
The electrostatic force between two point charges can be calculated using Coulomb's Law. In this case, the calculated force is 9.72 x 10^-3 N.
Step-by-step explanation:
The electrostatic force between two point charges can be calculated using Coulomb's Law, which states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Mathematically, it can be expressed as:
F = k * (q1 * q2) / r^2
where F is the electrostatic force, q1 and q2 are the charges, r is the distance between them, and k is the electrostatic constant.
In this case, the first charge is 3.5 x 10^6 C and the second charge is 5.2 x 10^(-6) C. Using the given values, we can calculate the electrostatic force:
F = (9 x 10^9 N·m²/C²) * ((3.5 x 10^6 C) * (5.2 x 10^(-6) C)) / (8.0 m)^2
F = 9.72 x 10^(-3) N
Therefore, the electrostatic force between the two charges is 9.72 x 10^(-3) N.
