A hollow cylinder has charge ' q ' C within it. If ' ' is the electric flux associated with the curved surface B , the flux linked with the plane surface A will be

Options

  1. A1 2 ( q ₀ - )
  2. Bq 2 ₀
  3. C3
  4. Dq ₀ -

Correct answer

A. 1 2 ( q ₀ - )

Step-by-step solution

As per Gauss' law the net flux through closed surface is, _ A + _ B + _ C = q ₀ Due to symmetry, the same flux passes through plane surfaces A and C, i.e., _ A = _ C array ll & 2 _A+ = q ₀ & _A= 1 2 ( q ₀ - ) array ( Given: _B= )
