Question #e0ae2

Answer 1

`"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.
