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