Question

Figure shows four charges q1,q2,q3,q4 fixed in space. Then, the total flux of electric field through a closed surface *, due to all charges q1,q2, q3 and q4, is

(a) not equal to the total flux through * due to q3 and q4

(b) equal to the total flux through * due to q3 and q4

(c) zero if q1+q2 = q3 + q4

(d) twice the total flux through * due to q3 and q4 if q1+q2 = q3 + q4

Answer 1

*Correct option:(b) equal to the total flux through due to q3 and q4**

Explanation:

Net flux is due to charge inside * only
