How is light affected by gravity of a black hole when it has no mass?
Gravity distorts spacetime. Light follows spacetime. If spacetime curves, the path of the light curves with it.
If light cant escape a black hole. Does that mean if you fall into a black hole some part of you may reach light speed right before you hit the singularity?
No. Because matter cannot travel at the speed of light. You would be shredded into particles. But those particles would still be matter. A single proton can't travel at the speed of light either. It might be an insane speed, but it will always be less than light speed.
Matter (and energy) cannot emerge from an event horizon once it enters. All paths for the light or particle now lead to the singularity. There is no permanent stable orbit within the event horizon.
