Q = magnitude of charge on each of the two point charge = 3.60 mC = 3.60 x 10⁻³ C
r = distance between the two point charges = 9.3 cm = 0.093 m
k = constant = 9 x 10⁹ Nm²/C²
F = magnitude of the force between the two point charges = ?
according to coulomb's law , force between two charges is given as
F = k Q²/r²
inserting the values
F = (9 x 10⁹) (3.60 x 10⁻³)²/(0.093)²
F = 1.35 x 10⁷ N
The magnitude of the force between two charges which are 9.3 cm apart is 1.35×10⁷ N
The magnitude of the force between the two charges can be obtained by using the Coulomb's law equation as illustrated below:
F = Kq₁q₂ / r²
F = (9×10⁹ × 3.6×10¯³ × 3.6×10¯³) / (0.093)²
F = 1.35×10⁷ N
