Question

1) 2 point charges are separated by a distance of 8 cm. The left charge is 48 mC and the
right charge is -16mC.
Using a full sheet of paper: draw the 2 charges separated by 8cm, centered in the sheet. (if you
are missing a ruler estimate 8cm as ⅓ a paper sheet length).
[6] a) Draw field lines to indicate the electric fields for this distribution.
[4] b) Draw 3 equipotential surfaces, 1 each, that pass:
-Through the center position between the charges.
-Through the point 4cm left of the left charge
-Through the point 4cm right of the right charge

2) In the charge distribution described above in Question #1, a test charge of 1C is
positioned at the center of these 2 charges.
[10] Determine the force on the test charge.
