STANDARD Physics Gauss's Law MCQ Question
A hollow cylinder has a charge q coulombs located within it symmetrically. If ϕ is the electric flux in units of volt-meter associated with the curved surface B, the flux linked with the plane surface A in units of volt-meters will be :-
q/ε₀ - ϕ
1/2 [q/ε₀ - ϕ]
q/2ε₀
ϕ/3
Correct Answer
Detailed Explanation
By symmetry, the same flux passes through plane surfaces A and C. Using Gauss's Law, the net flux through the closed surface is q/ε₀. Therefore, the flux linked with surface A is 1/2 [q/ε₀ - ϕ].
