A) 8 along positive X-axis
B) 16 along negative Y-axis
C) 16 along positive X-axis
D) 8 along, negative X-axis
Correct Answer: D
Solution :
We know that \[E=-\left[ i\frac{\partial V}{\partial x}+j\frac{\partial V}{\partial y}+k\frac{\partial V}{\partial z} \right]\] So, \[=-i\frac{\partial V}{\partial x}=-i\frac{\partial }{\partial x}(4{{x}^{2}})\] \[=-8x\,i\,V\,{{m}^{-1}}\] \[{{E}_{(1,0,2)}}=-8\,i\,V{{m}^{-1}}\]You need to login to perform this action.
