Questions & Step-by-Step Solutions
If the electric field at a point is zero, what can be said about the charges producing it?
Step 1: Understand that an electric field is created by charges.
Step 2: Know that each charge produces its own electric field.
Step 3: Realize that the total electric field at a point is the sum of all the electric fields from each charge.
Step 4: If the electric field at a point is zero, it means that the sum of all the electric fields from the charges is zero.
Step 5: This can happen when there are equal and opposite charges, meaning one positive charge and one negative charge are present.
Step 6: Therefore, if the electric field is zero, it indicates that the charges are balanced in such a way that their electric fields cancel each other out.
