What physical principle is reflected in the rule that electric field lines can never cross each other?

Which of the following conditions is required for a lightning discharge to occur between a cloud and the ground?

An object with a charge of $+Q$ experiences an electric force of $F$ in a certain field. If the object is replaced with one having a charge of $+3Q$ , what force will the new object experience at that same location?

Electric fields are a way of visualizing and calculating which of the four fundamental interactions of nature?

Beyond being a field that exerts force at a distance, what characteristic is shared by both the electric field and the gravitational field?

The principle of conservation of energy

The fact that field lines are physical substances

The law that opposite charges must attract

The requirement that the net electric field at any point has a single, unique direction

The cloud must be composed of only positive ions

The gravitational pull on the cloud must exceed the electric force

The ground must be completely neutral with no net charge
