Question
In this problem you will estimate the lifetime of electromagnetic energy at a rate given by P = -2kq^2a^2/3c^3, where a is acceleration. Assuminmg that the electron is one Bohr radius (0.0529 nm) from the center of the hydrogen atom. Calculate the energy of the electron and determine how long it wil take for all of this energy to be converted into electromagnetic waves, assuming that the rate calculated in part b remains constant through the electron's motion. b. was -2.90 eV/s. this is c, which is 4.69 x 10^11s
There is always one every chapter, this was it for this chapter! Thanks!
Explanation / Answer
The kinetic energy of the electron is
K = (1/2)mv^2
where m is mass of electron(9.1 * 10^-31 kg) and v is speed of electron
v = (2pi * r/T)
where r = 0.0529 nm = 0.0529 * 10^-9 m and T = 4.69 * 10^11 s
let t be the time taken for all of this energy to be converted into electromagnetic waves
we know that
v = u + at
where u = 0 and a is acceleration of electron
or t = (v/a)
