Q.
Consider the charge configuration and a spherical Gaussian surface as shown in the figure. When calculating the flux of the electric field over the spherical surface, the electric field will be due to
A) $q_{2}$
B) Only the positive charge
C) All the charges
D) $+ q_{1}\ and\ {- q}_{1}$
Explanation
(c) Electric flux may be due to the charges present inside the Gaussian surface, but for the purpose of calculation of electric field $E$ at any point we shall have to consider contribution of all the charges.
