When a glass rod is rubbed with a piece of silk it acquires +10 micro coulomb of charge. How many electrons have been transferred from glass to silk?

answered-by-expert Expert Answer
Charge on one electron = 1.602 × 10-19 C
 
Number of electrons in 10μC charge = ( 10 × 10-6 ) / ( 1.602 × 10-19 )
 
Number of electrons in 10μC charge = 6.242 × 1023
 
Hence 6.242 × 1023 electrons are transferred from glass to silk
