Final answer:
The magnitude of the net electrostatic force on q₁ can be calculated using the formula F = qE. Assuming q₁ = +1.00 μC and given E₁ = 8.99x10⁹ N/C, the magnitude of the net electrostatic force on q₁ is 8.99 N.
Step-by-step explanation:
The magnitude of the net electrostatic force on q₁ can be calculated using the formula F = qE, where q is the charge and E is the electric field strength.
Let's assume that the charge on q₁ is q₁ = +1.00 μC. Given the electric field strength at the origin due to q₁ is E₁ = 8.99x109 N/C, we can calculate the magnitude of the net electrostatic force on q₁ as:
F = q₁E₁ = (1.00x10-6 C)(8.99x109 N/C) = 8.99 N.
