2. Electric Potential and Capacitance
easy
On moving a charge of $20$ coulombs by $2 \;cm , 2 \;J$ of work is done, then the potential difference between the points is (in $volt$)
A
$0.2$
B
$8$
C
$0.1$
D
$0.4$
(AIEEE-2002)
Solution
(c) By using $W = Q.V $ $==>$ $\Delta V = \frac{2}{{20}} = 0.1\,volt$
