Question

Which of the following relation is correct regarding potential difference (V)?
(1) V=Fl/q (2)V=Fq/l (3)V=l/fq (4)V=q/Fl​

Answer 1

To find:

Relation between Potential difference, charge, force and length.

Calculation:

Let Potential difference be denoted as V , Charge be q , Force be F and length(Displacement) be l;

Potential difference is defined as the total work done to carry a charge from one point to another.

Here the force (F) refers to the the pushing effect that it carries the charge from one point to another.

$\therefore \: \sf{Potential \:Diff. = \dfrac{work}{charge} }$

$=> \: \sf{V = \dfrac{work}{charge} }$

$= > \: \sf{V = \dfrac{work}{q} }$

$= > \: \sf{V = \dfrac{force \times displacement}{q} }$

$= > \: \sf{V = \dfrac{F \times l}{q} }$

So, final answer is:.

$\boxed{ \: \rm{V = \dfrac{F \times l}{q} }}$
