energy= force X displacement right?
E=Voltage / distance & also E= Force/charge (E=Electric field strength) [i hope ur aware of this one]
so Voltage / distance= Force/charge
Force= Voltage X Charge / distance
Energy= Force X displacement
= Vq/ d X d
= Vq
Got it?

Thanks but is electric field strength the same as energy??

electric field: is a property that describes the space that surrounds electrically charged particles or that which is in the presence of a time-varying magnetic field. This electric field exerts a force on other electrically charged objects.
astarmathsandphysics:
No electric field is more closely related to force via the equation F=Eq=Electric field*charge
but also W=Fd=Force *distance=Eqd

ok i get this one but for energy=VQ i am still confused since Energy is not = to electric field strength so we can not substitute there right?? ??? :-\
