Question

$\text{A, B}$ and $\text{C}$ are three points situated in a uniform electric field, as shown. The electric potential is-

• A. Same at all the three points $\text{A, B}$ and $\text{C}$
• B. Maximum at $\text{A}$
• C. Maximum at $\text{B}$
• D. Maximum at $\text{C}$

Answer 1

The correct option is C Maximum at $\text{B}$

$E=-\frac{\Delta V}{\Delta x}$
The negative sign indicates that electric potential decrease as we move in the direction of electric field.

So, the magnitude of potential at the given points will be related as follows.
$V_B>V_C>V_A$
