Vedclass · Answer

(C) The equivalent current $i$ produced by a revolving charge is given by the formula $i = q 	imes 
u$,where $q$ is the charge and $
u$ is the frequency of revolution.Given:Charge of electron $q = 1.6 	imes 10^{-19} 	ext{ C}$Frequency $
u = 6.8 	imes 10^{15} 	ext{ rev/s}$Substituting the values:$i = (1.6 	imes 10^{-19} 	ext{ C}) 	imes (6.8 	imes 10^{15} 	ext{ s}^{-1})$$i = 10.88 	imes 10^{-4} 	ext{ A}$$i \approx 1.1 	imes 10^{-3} 	ext{ A}$Therefore,the correct option is $C$.

An electron (charge $= 1.6 \times 10^{-19} \text{ C}$) is moving in a circle of radius $5.1 \times 10^{-11} \text{ m}$ at a frequency of $6.8 \times 10^{15} \text{ rev/s}$. The equivalent current is approximately:
