A uniform electric field of $16 N C^{-1}$ exists in the vertically downward direction. The increase in electric potential as one goes up through a height of 75 cm.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 12 V
The change in electric potential (ΔV) is -
$ΔV=-E.d$
$=-(16).(-0.75)$
$=12V$
