Question

Two points A and B are lying in a uniform electric field as shown in figure.the correct relation about the potential at point A and point B will be
​

Answer 1

Solution :

$\sf\:V_{A}>\:V_{B}$

Because , potential decreases in the direction of electric field.

Extra Information :

Electric Potential

• Electric potential at a point is defined as external work done by a unit positive charge from infinity to that point without any acceleration.
• $\bf\:V=\dfrac{W_{\infty}}{q_{o}}$

Relationship between Electric potential and Electric Field

$\green{\bf\triangle\:V=-E\:\triangle\:r\:\cos\theta}$

Here , Negative sign implies that potential decrease in the direction of electric field.
