Q. If $4 \times 10^{2}\ eV$ energy is required to moves a charge of $0.25\ coulomb$ between two points. Then what will be the potential difference between them
A) $178\ V$
B) $256\ V$
C) $356\ V$
D) None of these
Explanation
(b) By using, $KE = QV \Rightarrow 4 \times 10^{20} \times 1.6 \times 10^{- 19}$
$= 0.25 \times V \Rightarrow V = 256\ volt$
