Q.No.168: - Rubber tires get charged from
friction with the road. What is the polarity of the charge?
Ans: - When two materials rubbed together then they will transfer
electron the one who get electrons become negatively charged and the other who
lose this charge gets positive charge. When tires rubbed with road then road
will transfer electrons to the tires hence tires get negative charge and the
road who transfer electrons get positive charge.
