Question

If the electron affinity of glass is less compared to electron affinity of animal fur, then the charge on a glass rod that has been rubbed with animal fur is

Answer 1

ANSWER:-

$\bigstar$

$\bull$ This is an example of the friction method,

$\bull$ a glass rod rubbed with fur becomes negatively charged,

$\bull$ Due to excess of electrons in rod, it becomes negatively charged while the fur with lost electrons,

$\bull$ becomes deficient of electrons. Thus, fur becomes positively charged
