Question

Two parallel plates are separated by $2\,cm$. If the potential difference between them be $20\,V$, then electric field between them is :

• A. 100 $NC^{-1}$
• B. 200 $NC^{-1}$
• C. 1000 $NC^{-1}$
• D. 2000 $NC^{-1}$

Answer 1

Answer: (C)

1000 $NC^{-1}$

Answer 2

$E = V/d$ = 20 $V$/0.02 m = 1000 V.
