The force between two charged particles is an electrostatic force. The intensity of this force is given by the following formula: [tex]F_c=k_c\frac{q_1q_2}{r^2}[/tex] Where q1 and q2 are charges r is the distance, and k_c is Coulomb's constant. Coulomb's constant has the value of: [tex]k_c=8.9875\cdot 10^9\frac{Nm^2}{C^2}[/tex] When we plug all the given values into the formula we get: [tex]F_c=8.9875\cdot 10^9\cdot\frac{-2\cdot3}{80^2}=-8425781 $N[/tex] Negative sign means that force is attractive.
