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} $
