A uniform electric field of $20 Vm^{-1}$ exists in the vertically downward direction. What will be increase in the electric potential as one goes up through a height of 60 cm?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 12 V
To calculate the increase in electric potential,
$ΔV=E×d$
$=20\frac{V}{m}×0.60m=12V$
