Question

if the electric potential at a single point is known. can E at the point be determined? if so, how ? if not why not ?​

Answer 1

Answer:

Explanation:The electric potential at a point is defined as the amount of work required to bring a unit positive charge from a reference point to that point, without changing its velocity.

The electric field at a point, on the other hand, is defined as the force experienced by a unit positive charge at that point.

These two quantities are mathematically related to each other.
