Physics - Electrostatics Question with Solution | TestHub

Potential difference between two points in a electric fields is,

${\mathrm{V}}_{\mathrm{A}}-{\mathrm{V}}_{\mathrm{B}}=\frac{\mathrm{W}}{{\mathrm{q}}_0}$

Where$\mathrm{W}$is work done by moving charge${\mathrm{q}}_0$from point$\mathrm{A}$to$\mathrm{B}$.

So,${\mathrm{V}}_{\mathrm{A}}-{\mathrm{V}}_{\mathrm{B}}=\frac{2}{20}=\text{0.1} \mathrm{V}$

(Here$\mathrm{W}=2 \mathrm{J},\mathrm{ }{\mathrm{q}}_0=20 \mathrm{C}$)
