In hydrogen atom, the electron makes 6.6×10156.6 \times 10^{15} revolutions per second around the nucleus in an orbit of radius 0.5×10−10m0.5 \times 10^{- 10}m. It is equivalent to a current nearly

A

1 A

B

1 mA

C

1μA1\mu A

D

1.6×10−19A1.6 \times 10^{- 19}A

Answer

1 mA

Explanation

Solution

i = qν =1.6×10−19×6.6×1015=10.56×10−4A=1mA= 1.6 \times 10^{- 19} \times 6.6 \times 10^{15} = 10.56 \times 10^{- 4}A = 1mA
