QAIPMT-2007-Ph-2364: NEET 2007 Physics - Class 12 AIPMT-2007-Ph-2364 Solution: A hollow cylinder has a charge q coulomb within it. If \( \) is …

A hollow cylinder has a charge q coulomb within it. If ϕ\phi is the electric flux in units of voltmeter associated with the curved surface B, the flux linked with the plane surface A in units of V-m will be

Multiple Choice Options

  • A q2ϵ0\frac{q}{2\epsilon_0}
  • B ϕ3\frac{\phi}{3}
  • C qϵ0−ϕ\frac{q}{\epsilon_0}-\phi
  • D 12(qϵ0−ϕ)\frac{1}{2}\left(\frac{q}{\epsilon_0}-\phi\right)

Step-by-Step Verified Solution

Let _ A , _ B and _ C are the electric flux linked with A, B and C. According to Gauss theorem, _ A + _ B + _ C = q _ 0 Since _ A = _ C _ 2 _ A = q _ 0 _ _ B _ 2 _ A = q _ 0 _ _     ( G i v e n _ B = _ ) _ _ A = 1 2 ( q _ 0 _ _ )
