Value of Ex depends on the value of x on x-axis as - Ex= 800 x^2
If I talk about the face of cube for which x=0,
Ex = 800 (x) ^2
= 800 (0) ^2
= 0
As electric flux depends on E as well as S, here for face-1, E=0, so flux will also be equal to 0.

Sir, आखिरी सवाल में doubt hai.... इसमें 60% फाइनल स्कोर लाने वाले विद्यार्थी 35% कैसे है. ये 60% होने चाहिए ना...क्योंकि remaining students 100-(30%+10%) = 60% है... Explain Please

Why not I think about it like this...4℅B=5℅G
B/G=5/4.
So total (B+G)=9=1800,,1=200
Then boys=5×200=1000 and girls=4×200=800????????
