A) \[12\,V{{m}^{-1}}\]
B) \[-6\,V{{m}^{-1}}\]
C) \[6\,V{{m}^{-1}}\]
D) \[-12\,V{{m}^{-1}}\]
Correct Answer: D
Solution :
Here, electric potential \[V=3{{x}^{2}}\] Electric field, \[E=\frac{\partial V}{\partial x}=-\frac{\partial }{\partial x}(3{{x}^{2}})=-6x\] \[\therefore \] \[{{E}_{(2,\,\,0,\,\,1)}}=-12\,\,V{{m}^{-1}}\]You need to login to perform this action.
