A) \[\frac{Q}{3{{\in }_{0}}}\]
B) \[\frac{Q}{6{{\in }_{0}}}\]
C) \[\frac{Q}{2{{\in }_{0}}}\]
D) \[\frac{Q}{{{\in }_{0}}}\]
Correct Answer: B
Solution :
Draw an imaginary square enclosing that point charge at the centre. Then from gauss law,\[\phi =\frac{{{Q}_{in}}}{{{\in }_{o}}}\] This is the flux passing through all the six surfaces. Therefore through one surface, \[\frac{1}{6}th\] of this flux will pass.
