A) 0
B) \[-6{{\phi }_{0}}{{\varepsilon }_{0}}\]
C) \[-2{{\phi }_{0}}{{\varepsilon }_{0}}\]
D) \[-\frac{6{{\phi }_{0}}}{{{\varepsilon }_{0}}}\]
Correct Answer: B
Solution :
[b] \[E=-\nabla \phi =-{{\phi }_{0}}2\,\,[x\hat{i}+y\hat{i}+z\hat{x}]\] \[={{\varepsilon }_{0}}\nabla .E=-2{{\varepsilon }_{0}}{{\phi }_{0}}\nabla .(x\hat{i}+y\hat{i}+z\hat{x})\] \[n=-6{{\phi }_{0}}{{\varepsilon }_{0}}\]You need to login to perform this action.
