Electrostatics Question 332

Question: A uniform electric field having a magnitude $ E _{0} $ and direction along the positive $ X- $ axis exists. If the potential $ V $ is zero at $ x=0 $ , then its value at $ X=+x $ will be [MP PMT 1987]

Options:

A) $ {V _{(x)}}=+xE _{0} $

B) $ V _{x}=-xE _{0} $

C) $ V _{x}=+x^{2}E _{0} $

D) $ V _{x}=-x^{2}E _{0} $

Show Answer

Answer:

Correct Answer: B

Solution:

$ \because E=-\frac{dV}{dX} $

therefore $ V _{x}=-xE _{0} $
