In hydrogen atom, the electron makes $6.6 \times 1 0^{15}$ revolutions per second around the nucleus in an orbit of radius $0.5 \times 1 0^{- 10} m$ . It is equivalent to a current (in mA) nearly :-

Answer:

1.05

Solution:

$i = q ν = 1.6 \times 1 0^{- 19} \times 6.6 \times 1 0^{15}$

$= 10.56 \times 1 0^{- 4} A$

$\approx 1.05$ to $1.06 mA$
