A) \[4\times {{10}^{3}}C\]
B) \[-4\times {{10}^{3}}C\]
C) \[\frac{-4\times {{10}^{3}}}{{{\varepsilon }_{0}}}C\]
D) \[-(4\times {{10}^{3}}){{\varepsilon }_{0}}C\]
Correct Answer: D
Solution :
\[\Delta \,\phi =4\times {{10}^{3}}-8\times {{10}^{3}}\] \[=-4\times {{10}^{3}}N-{{m}^{2}}/C\] According to Gauss's law Net flux through a closed, surface, \[\Delta \phi =\frac{1}{{{\varepsilon }_{0}}}q\]inside \[\Rightarrow \] \[q=-(4\times {{10}^{-3}}){{\varepsilon }_{0}}C\]You need to login to perform this action.
