Question Detail

PHY 102 Gauss's Law and Electrostatic Fields Objective Question

Question

What is the relationship between electric field E and electric potential V in one dimension?
Options
A E = dV/dx
B E = -dV/dx
Correct Answer
C E = V/d
D E = d²V/dx²
Correct Answer

Option B is the correct answer.

Detailed Explanation

The electric field is the negative gradient of the electric potential: E = -dV/dx (in one dimension). The field points from high to low potential.

Hint

Negative derivative.
