+4 / -1
A student performs an experiment with three unknown objects: X, Y, and Z. Object X repels a glass rod that has been rubbed with silk. Object Z repels a plastic ruler that has been rubbed with dry hair. Object Y is attracted to both Object X and Object Z. What is the nature of Object Y?
A
Positively charged
B
Negatively charged
C
Electrically Neutral
D
Could be Positive or Negative
Explanation
1. Object X is Positive (+): A glass rod rubbed with silk becomes positive. Since X repels it, X must also be positive. 2. Object Z is Negative (−): A plastic ruler rubbed with hair becomes negative. Since Z repels it, Z must also be negative. 3. Object Y is Neutral: A charged object would repel one of the others. Only an electrically neutral object is attracted to both positive and negative charges (due to induction/polarization).
