Electrostatic Potential and Capacitance

Question:

Electric potential at any point x, y, z in the space is given according to the following relation:

V= 4x²- 3x

What is the electric field at any point (x, y, z)?

Options:

(8x - 3) i

-(8x - 3) i

-8x i

8x i

Correct Answer:

-(8x - 3) i

Explanation:

E = -\(\frac{dV}{dx}\) = -\(\frac{d}{dx}\) 4x² - 3x = -(8x - 3)i
