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 $ $==>$ $\Delta V = \frac{2}{{20}} = 0.1\,volt$
