Electrostatics Ques 62
- 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: 62.(c)
Solution:
Formula:
- 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).
