  • Five charges q_1, q_2, q_3, q-4, and q_5 are fixed at their positions, as shown in Fig. 1.4. S is a Gaussian surface. Gauss's law is given by

Five charges q1, q2, q3, q4, and q5 are fixed at their positions, as shown in Fig. 1.4. S is a Gaussian surface. Gauss's law is given by

\oint_{s} E.ds=\frac{q}{\varepsilon _0}

Which of the following statements is correct?


A. E on the LHS of the above equation will have a contribution from q1, q5 and q3 while q on the RHS will have a contribution from q2 and q4 only.
B. E on the LHS of the above equation will have a contribution from all charges while q on the RHS will have a contribution from q2 and q4 only.
C. E on the LHS of the above equation will have a contribution from all charges while q on the RHS will have a contribution from q1, q3 and q5 only.
D. Both E on the LHS and q on the RHS will have contributions from q2 and q4 only..
Which of the following statements is correct?

 



 

Answers (1)

The answer is the option (b)

Explanation: The E on LHS of the vector sum of all the five charges while the q on RHS is the normal sum of charges enclosed by the surface, therefore, (b) is correct.
