Answer to Question #65021 in Physics for Helen

Question

7. Dr. Miller has been kidnapped and an imposter has created a problem on the physics
problem set. How do you know? Because it involves no algebra or other mathematics
whatsoever, and is simply drawing!4
(a) Sketch the electric field pattern around a pair
of point charges separated by a small distance, with the left one having a charge of
+1.0µC and the right one having a charge of +3.0µC (diagram provided). Be sure to
extend your drawn field lines a good distance out from the charges. (b) Then sketch
the electric field pattern if the +3.0µC charge (i.e., the one on the right) is replaced
by a charge of −2.0µC.
(a)
⊕ ⊕
+1.0µC +3.0µC
(b)
⊕
+1.0µC −2.0µC
