A) \[-24\,N\,{{m}^{2}}\,\,{{C}^{-1}}\]
B) \[24\,N\,{{m}^{2}}\,{{C}^{-1}}\]
C) \[32\,N\,{{m}^{2}}\,\,{{C}^{-1}}\]
D) \[-32\,N\,{{m}^{2}}{{C}^{-1}}\]
Correct Answer: A
Solution :
For electric flux passing through \[{{S}_{1}}\], \[{{\hat{n}}_{{{S}_{1}}}}=-\hat{j}\] (Left) \[{{\phi }_{{{S}_{1}}}}=-\left( 4\times {{10}^{3}}N\,{{C}^{-1}} \right)\,\left( 0\,.\,1\,{{m}^{2}} \right)\,\cos \,\left( 90{}^\circ -37{}^\circ \right)\] \[=-24\,N\,{{m}^{2}}\,{{C}^{-1}}\].You need to login to perform this action.
