Answer:

F = 1 N

Step-by-step explanation:

F = Gm₁m₂/r² + kq₁q₂/r²

F = (Gm₁m₂ + kq₁q₂) / r²

F = [6.674(10⁻¹¹)(0.50)(0.25) + 8.988(10⁹(5(10⁻⁶))(-2(10⁻⁶))] / 0.30²

F = 0.9986666667593611111...

F = 1 N

notice that the electrostatic force by itself results in an attraction of

0.99866666666666666666... N

The gravitational force is quite negligible in this example.
