ANSWER
Flux through surface A,
ϕ
A
=E×πR
2
ϕ
B
=−E×πR
2
Flux through curved surface, C=∫E.ds
=∫Edscos90
o
=0
∴ Total flux through cylinder =ϕ
A
+ϕ
B
+ϕ
C
=0
solution
Answer:
Electric field E through any area A -
Ф = E.A = EA cos θ
S.I unit - volt(m) or N-m²/c
where -
Flux through surface ФA = E×πR² and ФB = E×πR²
Flux through curved surface C = ∫ Eds = ∫ Eds cos 90° = 0
Therefore total flux through cylinder = ФA+ФB+ФC = 0
Thus, the total flux over curved surface of cylinder is zero
