A) \[{{S}_{1}}\]
B) \[{{S}_{2}}\]
C) \[{{S}_{3}}\]
D) same for all
Correct Answer: B
Solution :
Charge inside\[{{S}_{1}}={{q}_{2}}+{{q}_{3}}=-3\times {{10}^{-6}}C\] Charge inside\[{{S}_{2}}={{q}_{1}}+{{q}_{2}}+{{q}_{3}}\] \[=-1\times {{10}^{-6}}C\] Charge inside\[{{S}_{3}}={{q}_{1}}+{{q}_{2}}=5\times {{10}^{-6}}C\] Charge inside \[{{S}_{2}}\] is minimum. Thus, flux through \[{{S}_{2}}\] is minimum.
