Questions & Step-by-Step Solutions
If the electric potential at a point is 0 V, what can be said about the electric field at that point?
Step 1: Understand what electric potential means. Electric potential is a measure of the potential energy per unit charge at a point in an electric field.
Step 2: Recognize that 0 V means there is no potential energy at that point.
Step 3: Learn about the electric field. The electric field is a measure of the force that a charge would feel at a point in space.
Step 4: Know that the electric field is related to the electric potential. Specifically, the electric field is the negative change (or gradient) of the electric potential.
Step 5: If the electric potential is constant (like 0 V), it means there is no change in potential at that point.
Step 6: Since there is no change in potential, the electric field must be zero at that point.
