<span>A quadratic function is one of the form f(x) = ax^2 + bx + c, where a, b, and c are numbers with a not equal to zero.
In the given question, the only function that satisfies the condition of a quadratic function is f(x) = x^2 + 2x - 5 and thus is the correct answer to the question.</span>
Given that,
Charge q₁ = -0.004 C
Charge q₂ = -0.003 C
Distance between charges, d = 3 m
To find,
The electrostatic force between charges.
Solution,
The formula for the electrostatic force is given by :

So, 12000 N of electrostatic force is produced.

Answer:
Step-by-step explanation:
Use the formula of distance between the two points
and
,
Distance = 
1. Distance between A(3, 4) and B(8, 12),
AB = 
AB = 
= 
≈ 9.43
2. Distance between C(-2, 10) and D(3, -2),
CD = 
= 
= 
= 13.00
3. Distance between X(20, 4) and Y(17, 0),
XY = 
= 
= 
= 5.00
4. Distance between E(2, -1) and M(6, 9),
EM = 
= 
= 
= 10.77
