Which Gaussian surfaces have an electric flux of +q/εo through them

Click For Summary
SUMMARY

The discussion centers on identifying Gaussian surfaces that yield an electric flux of +q/εo. User "curious314" correctly deduces that option b is the appropriate choice, while options c and d are invalid due to charge cancellation and the presence of only negative charge, respectively. The consensus confirms that understanding the relationship between enclosed charge and electric flux is crucial for solving such problems.

PREREQUISITES
  • Understanding of Gauss's Law
  • Familiarity with electric flux concepts
  • Knowledge of charge distribution
  • Basic principles of electrostatics
NEXT STEPS

Which Gaussian surfaces have an electric flux of +q/εo through them?

I think is b
since in c, +q and -q cancel each other out, d is only -q

is that the right approach?

thanks!
