Question

The adjoining figure shows a spherical Gaussian surface and a charge distribution. When calculating the flux of electric field through the Gaussian surface, the electric field will be due to

• A. $+q_{3}$ alone
• B. $+q_{1}$ and $+q_{3}$
• C. $+q_{1},-q_{2}$ and $+q_{3}$
• D. $+q_{1}$ and $-q_{2}$

Answer 1

Answer: (C)

At any point over the spherical Gaussian surface, net electric field is the vector sum of electric fields due to $+q_{1}$, $-q_{2}$ and $+q_{3}$
