Answer 1

$E = - \frac{d V}{d l}$
where $E =$ Electric field intensity ; $V =$ Electric Potential ; $l =$ distance traveled in direction of electric field
Electric intensity at a point is the negative of rate of change of the electric potential at a point. So if a function is zero at a given point, the slope will not necessarily be zero.

Answer 2

E = - \frac{d V}{d l}

where

E =

Electric field intensity ;

V =

Electric Potential ;

l =

distance traveled in direction of electric field

Electric intensity at a point is the negative of rate of change of the electric potential at a point. So if a function is zero at a given point, the slope will not necessarily be zero.

Electric potential $V$ at some point in space is zero. Then at that point :

Electric intensity is necessarily zero.

Electric intensity is necessarily non zero.

Electric intensity may or may not be zero.

Electric intensity is necessarily infinite.

If a unit charge is taken from one point to another over an equipotential surface, then :

Potential at the point of a pointed conductor is greater than the other points on surface:

A point charge is brought in an electric field. The electric field at a nearby point:

When a charged conductor is placed near another conductor (which is connected to the ground), its potential :

In case of electronic current the charge flows from negatively charged body to the positively charged body. The body which is at higher potential is

Electric potential V at some point in space is zero. Then at that point :

Electric intensity is necessarily zero.

Electric intensity is necessarily non zero.

Electric intensity may or may not be zero.

Electric intensity is necessarily infinite.
