Answer to Question #138551 in Electric Circuits for Rasgel

Question

The electric potential at x=3.00 m is 120 V, and the electric potential at x=5.00 m is 190 V. What is the x-component of the electric in this region, assuming the field is uniform?

Answer 1

The x component of electric field is

$E_x=-\frac{dV}{dx}=--(\frac{190-120}{5.00-3.00}) = - 35 V$
