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 xx 10^(-9)` C
Charge of electron (e) `=1.6 xx 10^(-19)` C
Number of electrons transferred, `n=q/e = (50 xx 10^(-9))/(1.6 xx 10^(-19)) = 31.25 xx 10^(-9) xx 10^(-19)`
`n = 31.25 xx 10^(10)` electrons
