प्रश्न
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.
उत्तर
Charge produced in each object q = 50 nC
q = 50 x 10-9 C
Charge of electron (e) = 1.6 x 10-9 C
Number of electron transferred, n = `"q"/"e" = (50 xx 10^-9)/(1.6 xx 10^-19)`
=31. 25 × 10-9 × 1019
n = 31.25 x 1010 electrons
