infra red radiations cannot eject photoelectrons. 
infra red radiations cannot produce photocurrent.
explain if these two statements are true or false with explainantion?

Dear student 
The true and false of statement depends upon material you are using for photoelectric effect.
If energy of infrared is more than the work function of material then it will eject photoelectron and produce photocurrent.
But if it's less than work function of material then it can't produce photocurrent and photoelectron
