Question
A hollow cylinder has charge q C within it. if φ is the electric flux in unit of voltmeter associated with the curved surface B, the flux liked with the plane surface A in unit of voltmeter will be
Options
A.
B.
C.
D.
Solution
Let electric flux linked with surface A, B and C are φA, φB and φC respectively.
Thus φtotal = φA + φB + φC
∵ φA = φC
and φtotal =
(Form Gauss′s Law)
∴ = 2φA + φB But φB = φ (given)
Hence, = 2φA + φ
or - φ = 2 φA or φa = 
Thus φtotal = φA + φB + φC
∵ φA = φC
and φtotal =
(Form Gauss′s Law) ∴
= 2φA + φB But φB = φ (given)Hence,
= 2φA + φ or
- φ = 2 φA or φa = Create a free account to view solution
