Answer:
F=8.87 N
Explanation:
Coulomb's Law
The electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:
[tex]\displaystyle F=k\frac{q_1q_2}{d^2}[/tex]
Where:
[tex]k=9\cdot 10^9\ N.m^2/c^2[/tex]
q1, q2 = the objects' charge in coulomb
d= The distance between the objects in meters
Object 1 has a charge of
[tex]q_1=-2.3\cdot 10^{-6}\ c[/tex]
Object 2 has a charge of
[tex]q_2=-4.2\cdot 10^{-6}\ c[/tex]
They are separated by a distance of
d = 0.099 m
Calculate the force:
[tex]\displaystyle F=9\cdot 10^9\frac{2.3\cdot 10^{-6}*4.2\cdot 10^{-6}}{0.099^2}[/tex]
F=8.87 N
