The electric potential of a charge distribution is given by the equation V(x) = 3x2y2 + yz3 - 2z3x, where x, y, z are measured in meters and V is measured in volts. Calculate the magnitude of the electric field vector at the position (x, y,z) = (1.0, 1.0, 1.0)

The magnitude of the electric field is  

Explanation:

From the question we are told that

    The electric potential is  

Generally electric filed is mathematically represented as

So

at (x,y,z) = (1.0, 1.0, 1.0)

The magnitude of the electric field is  

answer; i believe that the correct answer is (d) a very small amount of mass

a and b sometimes have a positive value
