Electrostatics 3 Question 10

10. 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

$(2004,1 M)$

(a) $q _2$

(c) all the charges

(b) only the positive charges

(d) $+q _1$ and $-q _1$

Show Answer

Answer:

Correct Answer: 10. (c)

Solution:

  1. At any point over the spherical Gaussian surface, net electric field is the vector sum of electric fields due to $+q _1,-q _1$ and $q _2$. Don’t confuse with the electric flux which is zero (net) passing over the Gaussian surface as the net charge enclosing the surface is zero.

Hence, the correct option is (c).
