Question
Electric charge is uniformly distributed along a long straight wire of radius 1 mm. The charge per cm length of the wire is Q coulomb. Another cylindrical surface of radius 50 cm and length 1 m symmetrically enclose the wire as shown in the figure. The total electric flux passing through the cylindrical surface is ______.
Options
`"Q"/epsilon_0`
`(100 "Q")/epsilon_0`
`"10 Q"/(piepsilon_0)`
`"100 Q"/(piepsilon_0)`
Solution
Electric charge is uniformly distributed along a long straight wire of radius 1 mm. The charge per cm length of the wire is Q coulomb. Another cylindrical surface of radius 50 cm and length 1 m symmetrically enclose the wire as shown in the figure. The total electric flux passing through the cylindrical surface is `underline((100 "Q")/epsilon_0)`.
