flux = ∅
∅ = E.A

E = 500√x

area = A = 16×16cm²
A = 256cm²
= 2.56×10-²

so
net ∅ = (in) - (out)

∅in = 500√16×2.56×10-²
= 1280×4
= 5120

similarly
∅out = 5120√2

so ∅net = 5120(1-√2)

for enclosed charge
∅ = q/€

q = ∅€
= 5120(1-√2)×8.85×10-¹²
= -187.68×10-¹²

hope it helps you

riyatalukdar: i am so sorry but the answe is 1.88 X 10-11 C

riyatalukdar: Hmm u should have converted cm to m. Thank-you so much for your ans. Btw how did u get 512000√2

riyatalukdar: pls answer

Adityaadidangi: ok

Adityaadidangi: but i think charge is negative

Adityaadidangi: sorry but time of editing is expired
