Electrostatic Potential

Electrostatic Potential

, Electrostatic Potential
We have introduced Gauss law to
study electric field from a different
Point of view .
Here we
again study electric from a new point of view


This Point of view will involve energy .
In mechanics we studied force

from Newton's law as well as from energy point of view .

At the reference level let us assume that the
system has Zero Potential

If the object to Point A at night h, its Potential
energy . we move


be VA mg hi its potential energy will increase To
energy will =

increase its Potential
energy I may have to Perform some work .




From add to system by
thermodynamics we know we can
only energy a


work or by heat . ) If I move the object from point A to Point

B at
night hz I have to do work
