If a charge q is placed at the centre of a closed hemispherical non-conducting surface, the total flux passing through the flat surface would be :

JEE Main 2022 (Online) 27th June Evening Shift Physics - Electrostatics Question 105 English

Multiple Choice Options

  • A q∈0{q \over {{ \in _0}}}
  • B q2∈0{q \over {{ 2\in _0}}}
  • C q4∈0{q \over {{ 4\in _0}}}
  • D q2π∈0{q \over {{ 2\pi\in _0}}}

Step-by-Step Verified Solution

Flux passing through flat surface = Flux passing through curved surface.

So, ϕ=q2ε0\phi = {q \over {2{\varepsilon _0}}}
