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.

Answer»

Charge produced in each object q = 50 nC 

q = 50 x 10-9

Charge of electron (e) = 1.6 x 10-9

Number of electron transferred, n = \(\frac {q}{e}\)\(\frac {50 \times 10^{-9}}{1.6 \times 10^{-19}}\) 

=31. 25 × 10-9 × 1019 

n = 31.25 x 1010 

electrons 

Ans. n = 31.25 x 1010 electrons
