If F11 is zero , then why F22 is not zero???

[@amberpaige7322]

Hi, can you explain how F11=0 but F22 =/= 0?

This is just to make you understand ! If you look closely , the outward heat rays from 1 cannot reach one itself , you can do this by drawing radially outward lines from surface 1. But if you draw inward lines from 2 to 1 , some lines will hit 2 on the opposite side, so it is not zero.
