Problem $20($Halliday Problem $13\mathrm{.}16)$

In Fig. $13-40,$ a particle of mass $m_1=0\mathrm{.}67kg$ is a distance $d=23cm$ from one end of a uniform rod with length $L=3\mathrm{.}0m$ and mass $M=5\mathrm{.}0kg.$ What is the magnitude of the gravitational force vec$(F)$ on the particle from the rod?
