In a certain region, the electric potential due to a charge distribution is given by
the equation V(x,y,z) = 3x+ yz-3xz, where x, y, and z are measured in meters and
V is in volts. Calculate the magnitude of the electric field vector at the position
(x,y,z) = (11.2, 6.5, 10.7). Express your answer in V/m units, do not inset V/m
symbol, just insert the correct numerical value using 3 sig figs.
Hint: Here you want to find an expression for the electric field x component, the
y component, and the z component, then substitute with the given point value
to calculate the magnitude of the electric field vector. Double-check your math.
