"please see the fallowing details."

Explanation:

  • We firstly should remember the law of Coulomb.
  • Coulomb's law states that electrical charges apply electrical force to each other.
    F=k*(q_1*q_2)/(r^2)
    "where ; "q_1,q_2 " are charges,"
    "r distance between " q_1 and q_"
    k:"constant."
  • If the electrical charges have the same sign , then electrical charges push each other.
  • If the electrical charges have the opposite sign , then electrical charges pull each other.
  • The magnitude of the force exerted by A on B has shown in figure.

  • The magnitude of the force acted by B on A is the same but this force has opposite direction.
