Application +4 | -1

An electron (charge

= 1.6\,\, \times \,\,{10^{ - 19}}\,\,coulomb

) is moving in a circle of radius

5.1\,\, \times \,\,{10^{ - 11}}\,\,m

at a frequency of

6.8\,\, \times \,\,{10^{15}}\,\,revolutions/sec

. The equivalent current is approximately

View answer and explanation

Correct option: C

1.1\,\, \times \,\,{10^{ - 3}}\,\,amp

Option C (

1.1 \times {10^{ - 3}}\,amp

) is correct because it is the calculated equivalent current due to the electron's motion in a circle.
