#### Question

The electron in the hydrogen atom is moving with a speed of 2.3x106 m/s in an orbit of radius 0.53 Å. Calculate the period of revolution of the electron. (Π = 3.142)

#### Solution

v = 2.3xx10^6 m

r = 0.53Å = 0.53 xx 10^(-10)m

v = romega = r xx (2pi)/T

T = (2pir)/v = (2xx3.14xx0.53xx10^
(-10))/(2.3 xx10^6)

:. T = 1.44 xx 10^(-16) sec

f = 1/T = 6.9 xx 10^(15) Hz

Is there an error in this question or solution?
