Question

We now know that we can find the electric potential given the electric field. Conversely can we find the field given the form of the potential?. To find out please read the section 24-6 calculating the field from the potential. Select all correct statements about the electric field, E and the electric potential V: The net E is perpendicular to the equipotential surface the component of E parallel to the equipotential surface is zero the potential difference between points on the equipotential surface is zerco The net E is parallel to the equipotential surface The component of E in any direction is the negative of the rate at which the electric potential changes with distance in that direction

Explanation / Answer

field lines always perpendicular to equipotential lines.
So,

if net E is perpendicular to quipotential surafce then component along it will be zero.

equipotential surface means all points are at same potential.

and E = - dV/dr

Ans:

1. The net E is perpendicular to the equipotential surface.

2. the compoent of E parallel to equipotential is zero.

3. PD between points on equipotential surface is zero.

5. the component of E is any direction is the negative of rate at which EP changes in that direction.
