A small electric dipole of dipole moment magnitude \(p\) is located at a distance \(r\) from a fixed positive point charge \(+Q\). The dipole moment vector \(\vec{p}\) is oriented at an angle \(\theta\) relative to the outward radial unit vector \(\hat{r}\) pointing from \(+Q\) toward the center of the dipole. Which of the following expressions represents the radial component \(F_r\) of the net electric force acting on the dipole?
