Follow the procedure illustrated in Figure 22.5 to separate a pair of charged strips.

(a) How does strip B interact with a neutral object? How does strip T interact with a neutral object? 

(b) Create a third charged strip and see how it interacts with strip B and with strip T.

(c) Is strip T charged?

(d) Is strip B charged?

(e) Check what happens to the interactions with \(\mathrm{B}\) and \(\mathrm{T}\) strips when you discharge a \(\mathrm{B}\) or a \(\mathrm{T}\) strip by rubbing your fingers along its length.
