Physics · Electrostatic Potential
हिन्दीThe relation between electric field \( \mathbf{E} \) and electric potential \( V \) across closely spaced equipotential surfaces is given by \( |\mathbf{E}| = -\frac{\delta V}{\delta l} \). The negative sign indicates that:
View Answer & Solution
Correct answer · Option D
Electric field is in the direction in which potential decreases steepest / विद्युत क्षेत्र उस दिशा में है जिसमें विभव सबसे तेजी से घटता है
Explanation
The negative sign in \( E = -\frac{dV}{dl} \) shows that the electric field points in the direction of steepest decrease of electric potential.
