The gravitational pull of the moon is $(1/6)^{\text{th}}$ of the earth and the mass of the moon is $(1/8)^{\text{th}}$ of the earth. This implies that the:

  • A
    radius of the moon is $(1/4)^{\text{th}}$ of the earth's radius.
  • B
    radius of the earth is $(\sqrt{4/3})^{\text{th}}$ of the moon's radius.
  • C
    moon's radius is half that of the earth.
  • D
    radius of the earth is $(4/3)^{\text{th}}$ of the moon's radius.
