Question

Twoinsulatingplatesarebothuniformlychargedinsuchawaythatthepotentialdifferencebetweenthemis $V subscript 2 end subscript$ - $V subscript 1 end subscript$ =20V.(i.e.,plate2isatahigherpotential).The plates are separatedby d =0.1mand canbe treatedasinfinitelylarge.Anelectronisreleasedfromrestontheinner surfaceofplate1.Whatisitsspeedwhenithitsplate2?

$2.65 \times 10^{6} m / s$
$7.02 \times 10^{12} m / s$
$1.87 \times 10^{6} m / s$
$32 \times 10^{- 19} m / s$

The correct answer is: $2.65 cross times 10 to the power of 6 end exponent m divided by s$
