Answer:
1.9 km
Explanation:
The equation for vertical motion is ...
h(t) = -4.9t^2 +26t +20
This will have a zero near t = 5.988 seconds.*
The horizontal distance traveled in that time is ...
(310 m/s)(5.988 s) ≈ 1856 m ≈ 1.9 km

* The root of a quadratic can be found numerous ways. We choose the quick and easy: let a graphing calculator show it to you.
Answer:
Correct answer: There are four variables rather than two - The amount of charge q₁, the amount of charge q₂, the distance between the spheres and the relative dielectric permeability εr of the medium.
Explanation:
I assume you meant two spherical objects.
The force between two charged objects according to Coulomb's law is calculated by the formula:
Fc = 1/ (4 π ε₀ εr) · (q₁ · q₂) / d²
where :
- ε₀ is the dielectric permeability of the vacuum
- εr is the dielectric permeability of the medium
- q₁ the amount of charge of the first sphere
- q₂ the amount of charge of the second sphere
- d is the distance between the spheres
