Answer:
4.2 x 10⁷N
Explanation:
Given parameters:
Charge on ball:
q₁ = 3C
q₂ = 14C
Distance between balls = 9000m
Unknown:
Force acting on the two balls
Solution:
The force experienced by the two charges is given by coulombs law. It is mathematically expressed as;
F = [tex]\frac{k q_{1} q_{2} }{r^{2} }[/tex]
where k = 9 x 10⁹Nm²/C²
q is the charges
r is the distance
Input the variables and solve;
F = [tex]\frac{9 x 10^{9} x 3 x 14 }{9000}[/tex] = 4.2 x 10⁷N
