  • An electron is moving on a circle of radius 0.5 Å with a frequency of <img alt="5 \times 10^{16} \mathrm{~Hz}" src="https://entrancecorner.oncodecogs.com/gif.latex?5%20%5Ctimes%2010%5E%7

An electron is moving on a circle of radius 0.5 Å with a frequency of 5 \times 10^{16} \mathrm{~Hz} in anti – clockwise direction. The equivalent loop – current is:

Option: 1

4.0 mA (clockwise)


Option: 2

4.0 mA (anti – clockwise)


Option: 3

8.0 mA (clockwise)


Option: 4

8.0 mA (anti – clockwise)

Charges crossing a point per second is current i.e., \mathrm{e \times v } (this frequency of rotation is for a given radius)
\mathrm{\therefore \quad \mathrm{I}=1.6 \times 10^{-19} \times 5 \times 10^{16}=8 \times 10^{-3} \mathrm{~A}=8 \mathrm{~mA} }
The direction of the current is opposite to the motion of the electron i.e., clockwise.
