1.	The electric potential V at any point x,y,z (all in metre) in space is given by `V=4x^2` volt. The electric field at the point `(1m, 0, 2m)` is ……………`V/m`.A. 8, along negative X-axisB. 8, along positive X-axisC. 16, along negative X-axisD. 16, along positive Z-axis
Answer» Correct Answer - A Electric field, `E=-(dV)/(dr)=-(d)/(dx)(4x^(2))=-8x` `=-8(1)=-"8 Vm"^(-1)` Negative sign indicates E is along negative direction of X-axis.
