Electric charge is uniformly distributed...

Electric charge is uniformly distributed along a long straight wire of radius 1 mm. The charge per cm length of the wire Q coulomb. Another cylindrical surface of radius 50 cm and length 1 m symmetrical encloses the wire as shown in the figure. The total electric flux passing through the cylindrical surface is

A

`Q/epsilon_0`

B

`(100Q)/epsilon_0`

C

`(10Q)/(piepsilon_0)`

D

`(100Q)/(piepsilon_0)`

Text Solution

Verified by Experts

The correct Answer is:
B
The straight wire carries charge Q per cm. Hence, the total charge in one metre length will be 100Q. Therefore, the electric flux becomes `100Q//epsilon_0`.
