Which of the following shows the correct relation between electric Intensity E, and electric potential V:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → $E=\frac{-dV}{dr}$
The relation between the electric intensity (E) and the electric potential (V) is derived from the definition of potential gradient.
In one dimension, $E=\frac{-dV}{dr}$
