Type: MCQ-numerical-Medium-Class 12
Electric potential V at any point x, y, z in space is given by V = 6z². The value of the electric field at the point (2, -1, 3) is
A
24
B
-12
C
-36
D
12
Correct Answer
Option C
Detailed Explanation
The electric field is the negative gradient of the potential. Calculating the partial derivative with respect to z and evaluating at the given point gives 24.
