Gravity bends electric field lines
The electric field lines of a point charge go out radially from it (see figure 26.1). If the charged particle is replaced by a point source of light, the photons emitted by the source also propagate in the same way. In other words, the electric field lines track the photon path when the light source is replaced by a charge.
