Q
Q: If the electric potential at a point is 150 V and the electric field is directed towards the point, what can be said about the charge creating the field?
Solution: If the electric field is directed towards the point, it indicates that the charge creating the field is negative.
Steps: 4
Step 1: Understand that electric potential (measured in volts) indicates the amount of electric potential energy per unit charge at a point.
Step 2: Recognize that electric field lines point away from positive charges and towards negative charges.
Step 3: Note that if the electric field is directed towards the point where the potential is 150 V, it means the field is coming from a charge.
Step 4: Conclude that since the electric field is directed towards the point, the charge creating the field must be negative.
