1. _____The field lines emanate from the positive charge and terminate on the negative charge.
2. _____Field lines are evenly spaced between two oppositely charged plates.
3. _____The field lines extend to infinity
4. 12V battery is connected to two metal parallel plates separated by a distance of 0.5cm. Find the
magnitude of the electric field strength.
5. A 4C charge is at the origin (0,0) on a coordinate system. A point charge q2 = -3C is on the xaxis at (3,0) meters.
a. If the electric potential is taken to be zero at infinity, find the total electric potential due to
these charges at point P, with the coordinates (0, 0.4) m
b. How much work is required to bring a third point charge of 4C from infinity to P.
