The distribution of some charges on two Gaussian surfaces A and B are as shown in the figure. If _A and _B are electric fluxes linked with the surfaces A and B respectively. then _A _B =

Options

  1. A- 1 5
  2. B-3
  3. C- 3 2
  4. D- 3 4

Correct answer

D. - 3 4

Step-by-step solution

The distribution of charges on two Gaussian surfaces A and B are shown below Flux through a closed surface, = q_ net ₀ q_ net = net charge enclosed by the surface Here, (q_ net )_A= charge enclosed by surface A=q+3 q-2 q-5 q=-3 q And (q_ net )_B=-q+3 q+2 q=4 q So, _A _B = -3 q / ₀ 4 q / ₀ = -3 4
