The electrostatic potential V at any point (x,y,z) in space is given by V = 4x²

The x - component of electric field intensity at a $(-8\widehat{\mathrm{i}})$point (2, 0,2) is

The y - and z - components of the field are constant in magnitude.

The x - component of electric field intensity at any point is given by $(-8\mathrm{x}\widehat{\mathrm{i}})$

The y - and z - components of the electrostatic field at any point are not zero
