Final answer:
The electrostatic force on the positive charge is approximately -2.95 N.
Step-by-step explanation:
The electrostatic force between two 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. In this case, the electrostatic force on the positive charge can be found using the equation:
F = k * (q1 * q2) / r^2
Where F is the force, k is the electrostatic constant (approximately 9 x 10^9 Nm^2/C^2), q1 and q2 are the charges, and r is the distance between the charges.
Plugging in the values:
F = (9 x 10^9 Nm^2/C^2) * (5.9 C) * (-2.0 C) / (10 m)^2
F ≈ -2.95 N
Therefore, the electrostatic force on the positive charge is approximately -2.95 N.
