A) 32 V-m
B) 16 V-m
C) 12 V-m
D) 64 V-m
Correct Answer: D
Solution :
A square area of side 4 m parallel to y-z plane in vector form can be written as \[S={{4}^{2}}\hat{i}=16\hat{i}{{m}^{2}}\] Given, \[E=(4\hat{i}+3\hat{j})v{{m}^{-1}}\] Electric flux passing through the given area is \[{{\phi }_{E}}=E.S\] \[=(4\hat{i}+3\hat{j}).16\hat{i}=64\,V-m\]You need to login to perform this action.
