When two objects are rubbed with each other approximately a charge of 50 nC can be produced in each object . Calculate the number of electrons that must be transferred to produce this charge.

Explanation

Charge produced in each object q= 50 nC
`q = 50 xx10^(-9)C`
Charge of electron (e )`=1.6xx10^(-19)C`
Number of electron transferred n `=(q)/(e ) = (50xx10^(-9))/(1.6xx10^(-19)) = 31.25 xx10^(-9)xx10^(19)`
`n = 31.25 xx10^(10)` electrons
