2. Electric Potential and Capacitance
easy
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
${V_A} > {V_C}$

Solution
(b) Potential decreases in the direction of electric field. Dotted lines are equipotential lines
${V_A} = {V_C}$ and ${V_A} > {V_B}$
