Answer the following questions below. Be sure to show all of the necessary work.
1.
What is the potential difference between two parallel plates if a 42.2 μC charge gains
3.7 x 10-4 J of electric potential energy when moved from one plate to the other?
2.
A charge particle is moved through a potential difference of 154.5 V and experiences a
change of electric potential energy of 4.26 x 10-8 J. What is the charge of the particle?
3.
A 6.7 x 105 N/C electric field is set up between two parallel plates 11.3 cm apart. What is
the potential difference between the plates?
4.
Two parallel plates are separated by a distance of 6.48 cm. If the plates are connected to
the terminals of an 18.0 V battery, what is the strength of the electric field that is set up
between the plates?
5.
A 7.8 μC charge experiences a 2.6 x 10-3 N force while in an electric field, find the
strength of the electric field. If the field is being generated by parallel plates that are
12.8 cm apart, what is the potential difference between the plates?
6.
A pair of oppositely charged plates is separated by 9.45 cm. A potential difference of
285.0 V exists between the plates. What is the electric field that exists between the
plates? What would be the force exerted on an electron anywhere between the plates?
7.
What is the capacitance of a capacitor that has 7.9 x 107 C of charge and a potential
difference of 12.0 V?
