In a good insulator, electrons are usually

free to move around after an impurity has been added

To be safe in the unlikely case of a lightning strike, it is best to be inside a building framed with

either building will be just as safe or unsafe

The reason a rubbed balloon will stick to a wall is that

induced opposite charges in the wall are closer than the other wall charges

the charge is slightly sticky and acts like glue

electrons transfer back and forth between the wall and the balloon

balloon material simply sticks to walls

The direction of electric field lines show the

direction of the force on a positive test charge

When an electron is brought near a negatively charged sphere, its potential energy increases. The reason this happens is that

negative charges repel each other

work was done to bring the charges together

two like charges go from a position far apart to a position close together

When two negative charges are held close together and then released, the charges will

accelerate away from each other

move at a constant speed away from each other

Electric potential is defined as

electric potential energy of a charge divided by the quantity of charge

gravitational potential energy per charge

electric potential energy of a charge

electric potential energy of a charge multiplied by the quantity of charge

The electric field lines between two oppositely charged parallel metal plates will be

straight lines, randomly spaced

Two charges, +Q and −Q, are located two meters apart and there is a point along the line that is equidistant from the two charges as indicated. Which vector best represents the direction of the electric field at that point?

the electric field at that point is zero

A free electron is in an electric field. With respect to the field, it experiences a force acting:

anti-parallel (opposite in direction)

along a constant potential line

In which case does an electric field do positive work on a charged particle?

A negative charge moves opposite to the direction of the electric field.

A positive charge is moved to a point of higher potential energy.

A positive charge completes one circular path around a stationary positive charge.

A positive charge completes one elliptical path around a stationary positive charge.

If the distance between two isolated parallel plates that are oppositely charged is doubled, the electric field between the plates is essentially unchanged. However, the:

potential difference between the plates will double.

charge on each plate will double.

force on a charged particle halfway between the plates will get twice as small.

force on a charged particle halfway between the plates will get four times as small.

An ion is released from rest and moves due to the force from an electric field from a position in the field having a potential of 14 V to a position having a potential of 8 V. The ion:

can have either a positive or negative charge
