In a hydrogen atom, the electron and the proton are seperated by about 0.5 angstroms, 5.0×10−11 m. what is the acceleration of a

nadya68 [22]

The charge of proton and electron is equal in magnitude that is $1.6\times 10^{-19} C$ . The distance between electron and proton is $0.5 \AA$ or $5\times 10^{-11} m$ .

Force exerted on electron by proton is calculated as follows:

$F= \left | \frac{kq_{e}q_{p}}{r^{2}} \right |$

Here, k is Coulomb's constant, $q_{p}$ is charge on proton, $q_{e}$ charge on electron and r is distance between them.

Putting the values,

$F= \left | \frac{(8.99\times 10^{9}N m^{2}/C^{2})(1.6\times 10^{-19} C)(1.6\times 10^{-19} C)}{(5\times 10^{-11} m)^{2}} \right |=9.2\times 10^{-8} N$

Now, according to second law of Newton,

$F=m_{e}a$

Here, $m_{e}$ is mass of electron and a is acceleration.

Also, $1 N=1 kgm/s^{2}$

Rearranging,

$a=\frac{F}{m_{e}}=\frac{9.2\times 10^{-8} Kg m/s^{2}}{9.11\times 10^{-31} kg}=1.01\times 10^{23} m/s^{2}$

Thus, the acceleration of an electron in this atom is $1.01\times 10^{23} m/s^{2}$ .
