NEET 2014 Physics Electric Potential MCQ Question
Type: MCQ-numerical-Hard-Class 12
In a region, the potential is represented by V(x, y, z) = 6x – 8xy – 8y + 6yz, where V is in volts and x, y, z are in metres. The electric force experienced by a charge of 2 coulomb situated at point (1, 1, 1) is
A
6√5 N
B
30 N
C
24 N
D
4√35 N
Correct Answer
Option A
Detailed Explanation
The electric force is given by F = -q∇V. Calculating the gradient and substituting the values at point (1, 1, 1), the force is 6√5 N.
