Question

A uniform electric field pointing in positive x-direction exists in a region. Let A be the origin, B be the point on the x-axis at x = +1 cm and C be the point on the y-axis at y = +1 cm. Then the potentials at the points A, B and C satisfy:

• A. $V_A<V_B$
• B. $V_A>V_B$
• C. $V_A<V_C$
• D. $V_A>V_C$

Answer 1

The correct option is B $V_A>V_B$



Points A and C fall on a equipotential line, which implies $V_A=V_C$

As the point B is along the line ahead of A, by using $E=\frac{-\partial v}{\partial r}$
$V_B<V_A$
