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.
