A) \[Q/{{\varepsilon }_{o}}\]
B) \[Q/3{{\varepsilon }_{o}}\]
C) \[Q/4{{\varepsilon }_{o}}\]
D) \[Q/6{{\varepsilon }_{o}}\]
Correct Answer: D
Solution :
[d] According to Gauss' Law \[\oint\limits_{{}}{E.ds=\frac{{{Q}_{enclosed\,\,by\,\,closed\,\,surface}}}{{{\varepsilon }_{o}}}}=flux\] so total flux \[=Q/{{\varepsilon }_{o}}\] Since cube has six face, so flux coming out through one wall or one face is \[Q/6{{\varepsilon }_{O}}.\]
