If two points are at the same potential, does this mean that no net work is done in moving a test charge from one point to the other? Does this imply that no force must be exerted? Explain.
Step 1 of 1 </p>
Φa ;electric potential at point A
Φb ;electric potential at point B
U; electric potential difference between A and B
Step 2 of 3</p>
When a charged particle q goes from point A to B its potential energy change is;
Potential energy of the system changes when work is done. So work done is equal to change in potential energy.
A charged particle goes from point A to B having equal potentials. If point A an B have equal electric potentials, Potential difference between point A and B is zero.
