Back to 18.1 Static Electricity and Charge: Conservation of Charge

18.1 Exercise 11

Avg difficulty 2.5

In an experiment the following observations are made by a student for four charged objects W, X, Y, and Z:

A glass rod rubbed with silk attracts W.
W attracts Z but repels X.
X attracts Z but repels Y.
Y attracts W and Z.

Estimate whether the charges on each of the four objects are positive, negative, or neutral.
