Question

2. An electron is moving in a circular path of radius 5.1 x 10-'m
at a frequency of 6.8 x 1015 revolution/sec. The equivalent
current is approximately
(a) 5.1 x 10-'A
(b) 6.8 x 10-'A
(c) 1.1 x 10-A
(d) 2.2 x 10-A​

Answer 1

Answer:C

Explanation:

I=q/t

1/t = f

I=qf

For Electron q=1.6x10^-19

I= (1.6x10^-19)x(6.8x10^15)

I=1.1x10^-3
