Question

if w is the work done in moving a positive charge q from infinity to a certain point in the field,the electrical potentials v at this point would be equal to the​

Answer 1

Electric potential at a point in an electric field is defined as the potential energy per unit charge,and which is equal to work done in bringing a unit positive charge from infinity to that point.

Electric potential at a point in an electric field is defined as the potential energy per unit charge,and which is equal to work done in bringing a unit positive charge from infinity to that point.∴ϕ=W m

Answer 2

Electric potential may be defined as the amount of work done in moving a unit positive charge from infinity to a given point.

• If you have a positive charge q
• And you want to move it infinity to a certain point in the field
• And it takes an amount of work W to do it
• Then the electrical potentials v at this point would be equal to the​

        $\mathrm{V}=\frac{\mathrm{W}}{\mathrm{q}}$

Hence the electrical potentials is   $\mathrm{V}=\frac{\mathrm{W}}{\mathrm{q}}$
