A uniform electric field of magnitude E0 is directed along the positive X

Question

A uniform electric field of magnitude

E_{0}

is directed along the positive X - axis. If the potential V is zero at x = 0, then its value at X = + x will be

Options:

A . Vx=+xE0

B . Vx=−xE0

C . Vx=+x2E0

D . Vx=−x2E0

Answer: Option B
:
B

∵ E = - \frac{d V}{d X} \Rightarrow V_{x} = - x E_{0}
