Question

In hydrogen atom, the electron makes 6.6 x 1015revolutions per second around the nucleus in a orbit of radius 0.5 x 10-10m. It is equivalent to
(a) 1 A
(b) 1 mA
​(c) 1 microA
​(d) 1.6 x 10-19A

Answer 1

Answer:

(b)1mA

Explanation:

As we know that

I=Q/t=e/t

But

T=1/f

I=e×f

=1.69×10^-19×6.6×10^15

I=1.05×10^-3A

or I=1mA
