Electric charge is uniformly distributed...

Electric charge is uniformly distributed along a along straight wire of radius `1 mm`. The charge per centimeter length of the wire is `Q` coulomb. Another cyclindrical surface of radius `50 cm` and length `1 m` symmetrically enclose the wire ask shown in figure. The total electric flux passing through the cyclindrical surface is

A

`Q/(epsilon_0)`

B

`(100Q)/(epsilon_0)`

C

`(10Q)/((pi epsilon_0))`

D

`(100Q)/((piepsilon_0))`

Text Solution

Verified by Experts

The correct Answer is:
B
Total charge = 100Q ( Q charge per cm `:. 1 cm rarrQ , :. 1m rarr 100 cm rarr 100Q)`
`phi = (100Q)/(epsilon_0)`
