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 $x=\pm 1cm$ and C be the point on the y-axis at $y=\pm 1cm$. 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 $V_A>V_B$

Potential decreases in the direction of electric field. Dotted lines are equipotential lines
$\therefore V_A=V_C$ and $V_A>V_B$
