MCQ
Let $V$ and $E$ are potential and electric field intensity at a point then
  • A
    if $V = 0$ then $E$ must be zero
  • B
    if $V  \ne  0$ then $E$ can not be zero
  • C
    if $E \ne 0$ then $V$ can not be zero

Answer

Correct option: D.
if $V = 0$ then $E$ may be zero
d
if $v = 0\, E$ may or may not be zero
if $E = 0\, v$ may or may not be zero
