An electric field has
no direction.
only magnitude.
both magnitude and direction.
a uniformed strength throughout.
In the electric field surrounding a group of charged particles, field strength is greater where field lines are
thickest.
longest.
farthest apart.
closest.
A capacitor
cannot store charge.
cannot store energy.
can only store energy.
can store energy and charge.
What, if anything, is wrong with the field line diagram above?
It is wrong because the field lines should point towards the positive charges.
It is wrong because the field lines should be straight arrows.
It is wrong because field lines cannot cross each other.
The field line diagram is correct as drawn.
A capacitor stores an energy of 10J. If its area is doubled and the distance between its plates is cut in half, what would the new stored energy be?
2.5 J
5 J
20 J
40 J
How can a neutral object become charged?
by being dipped in water
by being stuck to the desk with tape
by allowing gravity to work on it
by having electrons added or removed
What happens to the field strength as the distance between two charged objects decreases?
the strength stays the same
the strength increases
the strength decreases
the strength fluctuates between positive and negative
