Question on: JAMB Physics - 1998
An ebonite rod rubbed with fur attracts a glass rod rubbed with silk because
A
ebonite has a negative charge while glass has a positive charge
B
ebonite has a positive charge while glass has a negative charge
C
both have negative charges
D
both have positive charges
Ask EduPadi AI for a detailed answer
Correct Option: A
When an ebonite rod is rubbed with fur, it gains electrons and becomes negatively charged. When a glass rod is rubbed with silk, it loses electrons and becomes positively charged. Since opposite charges attract, the ebonite rod (negative) attracts the glass rod (positive).
