Electric potential at any point x, y, z in the space is given according to the following relation:
V= 4x2- 3x
What is the force experienced by a charge particle q at point (1, 1, 1)?
Answer & explanation
Correct answer: option 1
F = q * E
E = -\(\frac{dV}{dx}\) = -\(\frac{d}{dx}\) 4x2 - 3x = -(8x - 3) i
|E|(1,1,1) = - 5 i
$\vec{F} = -5q\hat{i}$
