Question

4. Suppose you lifted strips of tape similar to those in Activity 1, resulting in a charge of +100 nC uniformly distributed on one strip. This strip is 20 cm long, and hung from its top. You next move a probe rod with a +200 nC charge to 5 cm away from the base of the strip of tape. (a) Ignoring any deflection of the tape (which would be slight from this distance), what is the strength of the electric field caused by the probe rod at the bottom point of the tape? (3 pts) (b) Ignoring any deflection of the tape (which would be slight from this distance), what is the strength of the electric field caused by the probe rod at the middle point of the tape? (3 pts) (c) Use your answers to the questions above to explain the qualitative behavior of charged tape that you saw in this lab. (3 pts)
