A) \[+17\,V{{m}^{-1}}\]
B) \[-17\,V{{m}^{-1}}\]
C) \[+12\,V{{m}^{-1}}\]
D) \[-12\,V{{m}^{-1}}\]
Correct Answer: C
Solution :
\[V=3{{x}^{2}}+5\] \[E=-\frac{dV}{dx}=-\frac{d}{dx}(3{{x}^{2}}+5)=-6x\] At \[(-2,1,0),E=-6(-2)=12\,V/m.\] Hence, the correction option is [c].You need to login to perform this action.
