A uniform electric field, with a magnitude of 6450 N/C, is directed parallel to the positive x-axis.  If the potential at x = 3.0 m is 1000 V, what is the change in potential energy of a proton as it moves from x = 3.0 m to x = 1.0 m? (qp = 1.6 x 10-19 C)

What is the direction of the electric field shown?  

Two charges are placed a distance of 0.05 cm apart.  One charge has a value of +4nC and the other a value of  -4 nC.  What is the electric force (F) between these two sets of charges? (ke = 8.99 x 109 N·m2/C2)

What does a multi-meter measure?

Consider the three point charges at the corners as shown, where x = 7cm and y = 2 cm q1 = 2.00 x 10-6C q2 = 4.00 x 10-6 C q3 = 7.00 x 10-6C.     What is the electric potential (in V) at the upper-right corner of the rectangle?

Where is the Electric Field the maximum in a dipole?

If body P, with a positive charge, is placed in contact with body Q (initially uncharged), what will be the nature of the charge left on Q?
