Question

1) What is the electric flux through the surfaces indicated below, where each point charge has magnitude of +/- e

a) left half circle only
b) right half circle only
c) lower left segment only
d) upper left segment only
e) entire triangle

2) What is the magnitude of the electric field 1 cm above a sheet with uniform surface charge density sigma = 20 nC/m^2?

3) What is the charge on an ion that gains a potential energy of 3.4 pJ when it moves through a potential difference of 1900 V?

4) A charge q1 = 2 uC is located at the position (x,y) = (5 cm, 7 cm). A second charge q2 = 1 uC is located at the position (x,y) = (5 cm, 0 cm). Calculate the electric potential at the origin.

5) Calculate the work required to move a third charge q3 = 3 uC to the origin, from infinity.
