Assertion (A): According to classical theory, the proposed path of an electron in Rutherford atom model will be parabolic.
Reason (R): According to electromagnetic theory an accelerated particle continuously emits radiation.
Reason (R): According to electromagnetic theory an accelerated particle continuously emits radiation.
View answer and explanation
Correct option: B
Both (A) and (R) are true and (R) is not the correct explanation of (A)
Option B (Both (A) and (R) are true and (R) is not the correct explanation of (A)) is correct because while both the parabolic path and radiation emission are true statements, the radiation emission doesn't directly cause the parabolic path.

Which of the following statements are true regarding Bohr’s model of hydrogen atom
(I) Orbiting speed of electron decreases as it shifts to discrete orbits away from the nucleus
(II) Radii of allowed orbits of electron are proportional to the principal quantum number
(III) Frequency with which electrons orbit around the nucleus is discrete orbits is inversely proportional to the cube of principal quantum number
(IV) Binding force with which the electron is bound to the nucleus increases as it shifts to outer orbits
Select correct answer using the codes given below
A particle moving with a velocity of of that of light will cross a nucleus on about A hydrogen atom is in ground state absorbs a photon of ultraviolet radiation of wavelength . Assuming that the entire photon energy is taken up by electron with what KE will the electron be emitted. In a spectrum of hydrogen atom, the ratio of shortest wavelength in Lyman series to longest wavelength in Paschen series is When the wave of hydrogen atom comes from infinity into the first orbit then the value of wave number is To explain his theory, Bohr used
