A charge ${q_1}$ exerts some force on a second charge ${q_2}$. If third charge ${q_3}$ is brought near, the force of ${q_1}$ exerted on ${q_2}$

  • A

    Decreases

  • B

    Increases

  • C

    Remains unchanged

  • D

    Increases if ${q_3}$ is of the same sign as ${q_1}$ and decreases if ${q_3}$ is of opposite sign
