None of the above
The force on a charge in a static electric field is not determined by potential alone; it depends on the electric field, which is not given.

Q
Q: If the electric potential at a point is 300 V and a charge of 3 C is placed at that point, what is the force acting on the charge?
Solution: The force on a charge in a static electric field is not determined by potential alone; it depends on the electric field, which is not given.
Steps: 4
Step 1: Understand that electric potential (measured in volts) tells us how much potential energy a charge would have at a point in an electric field.
Step 2: Recognize that the force acting on a charge in an electric field depends on the electric field strength (measured in volts per meter), not just the electric potential.
Step 3: Note that the electric potential is given as 300 V, but we do not have information about the electric field strength at that point.
Step 4: Conclude that without knowing the electric field strength, we cannot calculate the force acting on the charge.
