#### Question

The electron in the hydrogen atom is moving with a speed of 2.3x10^{6} 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?
