Find the potential difference between 2 pts given the electric fields at all points in the surroundings.
Approach-
Let one point be A and one point be B.
Thus, Va - Vb=- integral from b to a(E vector. dr vector)
Also I can write the opposite equation, that is
Vb -Va = -integral from a to b( E vector.dr vector)
In second case angle between dr and E vector will be exactly supplementary of 1st case. Thus taking the dot product in first case to be positive, the dot product in the second case would be negative. Also the integral from a to be of anything would be exactly the negative of the integral from b to a.
This leads to Va -Vb=Vb-Va which is surely wrong...
I can't really understand what I have done wrong here...
