# When we move a charge of 20 coulombs by a distance of 2 cm, then 2 Joule of work is done. What is the potential difference between the initial and final position of charge? Option 1) 4 V Option 2) 0.6 V Option 3) 0.1 V Option 4) 8 V

As we learnt in

Electric Potential -

$\dpi{100} V=\frac{w}{q_{0}}$

- wherein

w - work done

q0 - unit charge.

$\Delta V = \frac{\Delta w}{q} = \frac{2J}{20C} = 0.1 \ V$

Option 1)

4 V

This option is incorrect

Option 2)

0.6 V

This option is incorrect

Option 3)

0.1 V

This option is correct

Option 4)

8 V

This option is incorrect
