Question
A cylinder of radius R and length L is placed in a uniform electric field E parallel to the cylinder axis. The total flux from the curved surface of the cylinder is given by
Options:
A .  2πR2E
B .  πR2E
C .  (πR2−πR)E
D .  zero
E .  If assertion is false but reason is true.
Answer: Option D
:
D
Φ=Φ1+Φ2+Φ3Φ1=EAcos180=EA
=EA+EA+0Φ2=EAcos0=+EA
=0Φ3=EAcos90=0(Since Angle between E and A(Lateral surface) is always 90)
We only need to find Φ3
A Cylinder Of Radius R And Length L Is Placed In A Uniform E...
